The mods are pretty good at pm'ing a warning to offenders as well as locking threads, merging topics, etc.
It could be a case of overlooking, hence there is a report button on each and every post.
If it offends you... report it,
[quote:2r6onbur] use the report button to alert a moderator to the problem and one of us will take care of it. This includes spam posts.
if it is legit reporting, then the mods will act upon it. Else, you can expect a warning and explanation as to why.
There are a few posters who get carried away with posting, and I know they have had multiple warnings, and they are generally under 15 years of age. So the mods take pity on them and are trying to train them, steer them to proper etiquette. I just block them personally, as I couldn't be bothered reading anything they have to say Add them to foe list.
