I don't mind people posting links on other boards as part of a discussion. What I do mind, however, is someone signing up as "9/11 truther", and doing nothing but spamming links to this all over completely unrelated tech support forums. The staff is distracted from actually helping people because they have to clean up the mess.
If you want lots of people to see what you feel is important, fine, that's quite normal. But all this spamming is doing is pissing people off, and I understand you would like them to be sympathetic to your point of view, correct?
In that case I would recommend you don't behave like the people who offer to enlarge certain parts of the male anatomy.
