Thanks for the clarification, I can see what you mean however I perhaps would have appreciated a warning beforehand. Or perhaps if there was a topic in a very prominent position on the forum explaining what to be careful of people wouldn't get tripped up when they thought they were within the guidelines.
AFAIK the first temp ban is considered a warning. It might be a harsh one, but apparently thats the way mods handle the board.
The linked thread is trying to change that, but it is "unofficial" since there will be no official rules. There are several reasons.
#1 It would (according to some mods) make it to easy to find loop holes in those rules and exploit those. I can understand this to a part. Ofc it is not helping to say: you must post at least 17 words or its spam. Most of the spammers/spambots post several hundred words. Its also easy to make a sentence longer, but still have the same meaning. Yet I think vague rules would help.
#2 All the rules are (similar to laws) open to interpretation by the mod that is enforcing the rule. Thus it would not be wise to make the rule to tight.
#3 There are stickies in several parts of the board with rules, yet there has not been a central post. This is partly because not all of the rules apply to all of the boards.
Here [1] is the post where it was stated that paid sigs increase your chance to get banned.
Its -again- not official, since there is no one answer (see the last post [2])
never happend to me but there should be 1-2 warnings before you get temporary banned in my view!
While your posting structure might be similar and you have even more posts/day you do not sell your signature. It makes a big difference.
If you sell your signature consider yourself under constant watch. There have been lengthy discussions if selling the signature should be allowed or not, since it apparently (again "quoting" mods) increases spam. This is a very delicate topic. Allowing paid signatures enables e.g. students or kids to earn some coins which would otherwise be unable to buy or earn them. On the other hand if unchecked it results in spam. Those running the campaigns sometimes can not controll this and rely partly on the mods/staff. Which makes sense, for them the content of the post is less important than the "coverage". The more times the signature is shown the better, no matter what is written above.
