There are ramifications for violating the tos - stern notes (PM's) from the hall monitor, warnings from same and banning are some of the tools in the box.
We try and be fair about this, but of course not all will agree with mod decisions.
We in fact can cross check ip addresses, if a problem member shows back up under an assumed name it is easily identified and dealt with.
Freedom of speech is very important to us and we definitely attempt to afford leeway, however once the conversation crosses over into personal attack and name calling the gloves come off & Mod's are allowed to use their best discretion.
The system works pretty well but if one thinks it's bias or not fair, I suggest you come and sit on the fence with us - it's not as easy as you may think.
