And if you are a regular trusted member of the forum then why not get some payback for that
That is not the scenario discussed. The scenario is hit the forum, pick a thread that has the right context for your link, give an answer, and drop a link. That's called a driveby link drop. Forum admins are quite familiar with it.
Can a trusted forum member drop a link to their own site? Let's cut through the BS speculation and get to the reality of the situation. :)Are the people who are considering forum link drops going to spend a year posting on twenty different forums in order to become a "trusted member" so that they can then, a year later and after 300 posts on these twenty different forums (6,000 posts), they post their link?
This why I call it BS Speculation. It's a tremendous amount of work (6,000 posts on twenty different forums) for little reward. People inclined to drop links in forums will not put in that kind of work. The effort is better spent acquiring links elsewhere.
