It is annoying, and such posts can often be reported as spam, especially if they have little to nothing to do with the topic of discussion.
If there is more than an obvious intention (and here it is undoubted), then reporting a post for spam/shilling is not something that will solve the problem, at least not within a normal time frame. BG shills also appeared on the ATT forum, but their admin reacted literally in a few minutes after the report and cleaned them from the system. Some obviously disagree with such actions, but is there any logic in letting someone make a few hundred spam posts in order to be punished?
