Academia - Scooping content from Academia SE - is that ok?
See A site (or scraper) is copying content from Stack Exchange. What do I do?. This post details:
- When to report such sites,
- When not to report such sites,
- How to report such sites
The site you have given as an example does not meet the attribution requirements, so you should report it.
You can easily find on their website an answer of yours which has
- no link whatsoever back to your post,
- no mention of your username or name,
- no mention of the license, even less a link to it.
This is an egregious copyright violation and you, as an author, can and should send a DMCA takedown notice to defend the commons. Follow the DMCA instructions of the registrar, which is based in USA and can shut down the domain. StackExchange has less power than you in this matter, though it's nice to notify them with the general procedure linked above.
Update: newtips.co is responsive to DMCA notices, they removed a post of mine; pcusernet.com is still up; bighow.org is still up, I now sent a notice to their host ramnode.com as they are in violation of AUP.
Update 2: pcusernet.com is blocked on Firefox and Chromium as malware site, bighow.org continues business as usual but has removed my post. Do send complaints for every plagiarism of your own posts, eventually they'll give up!
