I started this blog in 2012; in these 3 1/2 years it has been a wonderful way to channel some of my interests in image processing, geophysics, and visualization (in particular colour), and more recently Python.
Starting with 2016 I would like to concentrate my efforts on building useful (hopefully) and fun (for me at least) open source (this one is for sure) tools in Python. This is going to be my modus operandi:
do some work, get to some milestones
upload the relevant IPython/Jupiter Notebooks on GitHub
The implementation of the finished app involves using morphological filtering and other image processing methods to enhance the sketch image and convert it into a model with discrete bodies, then pass it on to Agile’s modelr.io to create a synthetic.
I think openness in geoscience is very important, and I feel we all have a duty to be open with our work, data, ideas when possible and practical. I certainly do believe in sharing a good deal of the work I do in my spare time. So much so that when I started this blog there was no doubt in my mind I would include an agreement for people to use and modify freely what I published. Indeed, I venture to say I conceived the blog primarily as a vehicle for sharing.
Some of the reasons for sharing are also selfish (in its best sense): doing so gives me a sense of fulfillment, and pleasure, as Matt Hall writes in Five things I wish I’d known (one of the essays in 52 You Should Know About Geophysics), you can find incredible opportunities for growth in writing, talking, and teaching. There is also the professional advantage of maintaining visibility in the marketplace, or as Sven Treitel puts it, Publish or perish, industrial style (again in 52 You Should Know About Geophysics).
How I used to share
At the beginning I choose an Attribution-NonCommercial-ShareAlike license (CC BY-NC-SA) but soon removed the non-commercial limitation in favour of an Attribution-ShareAlike license (CC BY-SA).
A (very) cold shower
Unfortunately, one day last year I ‘woke up’ to an umpleasant surprise: in two days an online magazine had reposted all my content – literally, A to Z! I found this out easily because I received pingback approval requests for each of them (thank you WP!). Quite shocked, I confess, the first thing I did was to check the site: indeed all my posts were there. The published included an attribution with my name at the top of each post but I was not convinced this would be fair use. Quite the contrary, to me this was a clear example of content scraping, and the reason why I say that is because they republished even my Welcome post and my On a short blogging sabbatical post – in the science category! – please see the two screen captures below (I removed their information) of the pingbacks:
If this was a legitimate endeavour, I reasoned, a magazine with thoughtful editing, I was sure those two posts would have not been republished. Also, I saw that posts from many other blogs were republished en masse daily.
Limitations of Creative Commons licenses
I asked for advice/help from my twitter followers, and on WordPress Forums, while at the same time started doing some research. That is when I learned this is very common, however being in good company (google returned about 9,310,000 results when searching ‘blog scraping’) did not feel like much consolation: I read that sites may get away with scraping content, or at least try. I will quote directly from the Plagiarism Today article Creative Commons: License to Splog?: “They can scrape an entire feed, offer token attribution to each full post lifted (often linking just to the original post) and rest comfortably knowing that they are within the bounds of the law. After all, they had permission …Though clearly there is a difference between taking and reposting a single work and reposting an entire site, the license offers a blanket protection that covers both behaviors”.
It is possible to switch to a more restrictive Creative Commons license like the Attribution-NonCommercial-NoDerivs (perhaps modified as a CC+), but that only allows to cut your losses, not to fight the abuse, as it is only on a going-forward basis (I read this in an article, and jotted down a note, but I unfortunately cannot track down the source – you may be luckier, or cleverer).
Then I was contacted by the site administrator through my blog contact form (again I removed their information), who had read my question on the WordPress forum:
Your Name: ______
Your Email Address: ______
Your Website: ______
Your site is under a CC license. What’s the trouble in republishing your content?
Subject: Your license
Time: Thursday July 26, 2012 at 12:26 am
IP Address: ________
Contact Form URL: http://mycartablog.com/contact/
Sent by an unverified visitor to your site.
I responded with a polite letter, as suggested by @punkish on twitter. I explained why I thought they were exceeding what was warranted under the Creative Commons license, that republishing the About page and Sabbatical posts was to me proof of scraping, and I threatened to pursue legal recourse, starting with DMCA Notice of Copyright Infringement. Following my email they removed all my posts from their site, and notified me.
I think I was fortunate in this case, and decided to take matters into my own hands to prevent it from happening again. Following my research I saw two good, viable ways to better protect my blog from scraping whole content, while continuing to share my work. The first one involved switching to WordPress.org. This would allow more customization of the blog, and use of such tools as the WP RSS footer plugin, which allows to Get credit for scraped posts, and WP DMCA website protection. Another benefit of switching to WordPress.org is that – if you are of belligerent inclination – you can try to actively fight content scraping with cloacking. Currently, although it is one of my goals for the future of this blog, I am not prepared to switch WordPress.com due to time constraints.
I customized my statement to reduce as much as possible the need for readers to ask for permission by allowing WorPress reblogging and by allowing completely open use of my published code and media. Below is a screen capture of my statement, which it is located in the blog footer:
I hope this will be helpful for those that may have the same problem. Let me know what you think.
