One way to find them all would be if Bitcointalk creates a page like
patrol, but for edited posts only.
This could work. The edited time could also be moved up to when the post or reply will not be likely seen by others.
For example, a post that was edited after 15-20 minutes are still very much new and does not need to be added to such a patrol list.
I'm sure Google hates this SEO strategy it could affect also our forum it must be reported to mods.
We are still very far away from the frequency of spam links that will hurt the forum's SEO ratings from google or any other search engine.
For most cases you will have to actually as a forum be encouraging such spam links and to a very high degree for it to affect the website.
The admin also seems to not care much about the rating of the forum om search engines nor take any professional action to improve it.
