Okay, this happened one time too often, and it's somewhat annoying, so here are some basic rules.
1) When advertising your comic, link to it. And I do mean link. I don't mean paste the url, or just expect people to click your profile and then the comic, link to it with proper bbcode, i.e. [url]your comic url - WITH http://[/url]
2) Don't reply to the post every few hours or so. Do it reasonably. If your thread has sunken down a little and it's been a reasonable time since you last replied/made a thread about it, it's ok. Show some restraint.
now, I didn't name an exact time period, but I expect you to use your common sense here. At least two days.
3) Only active members of the community may advertise here. That means either active on the forums (more than 30 posts and still active) or hosting a comic on here.
4) You may only advertise webcomics if they are hosted on comicfury.
