Am i the op of any of those threads?
After a quick check the answer is no.
Yet neither literacy nor understanding Bitcoin appear to be requirements for joining a signature campaign, which is the problem in the first place.
I'd safely say that the majority has a very limited knowledge regarding Bitcoin or none at all (although they know how to use a wallet and generate addresses). This is quite unfortunate to see on a forum dedicated to Bitcoin.
I've long said signature campaigns could help improve the post quality of the forum but that would only happpen if every campaign only accepted quality posters and didn't just pay anyone and everyone regardless of post quality and ways to force campaigns to do that is being discussed also.
This is far from what we have in reality. We could set up regulations that require better quality control though.
