If you want to troll to create shits & giggles and talk shit about every artist and fandom, that will not be tolerated and you will be banned.
The new rules are more relaxed for a purpose.. if you have an issue with a certain group or fandom, you can discuss it properly in a sophisticated way, or as sophisticatedly as possible. But just creating a ton of threads trashing every fandom will not be tolerated and you will be banned.
The entire purpose of making the rules more lax is to encourage more opinions and free speech regarding your feelings towards a certain artist, performance, or song... don't get the wrong idea that more laxed rules means total carnage.
For example:
This is ok:
"I think X artists latest release is really bad, because the concept is so strange, and the song is really forgettable, there is no catchy hook."
This has an actual reason why, and it's not out of hatred.. it's just a personal opinion, and that is fine.
This is not ok:
"I think X artists song is really bad because they aren't charting well and they are total flops, and they are ugly."
This is just shit stirring for no reason without any real reason and it won't create any "intellectual" discussions, conversations, or musical theory (unlikely but when it happens it's mind blowing) other than the fandom talking shit back to you. Which is probably what you wanted, but it will result in a ban.
TLDR: Don't create threads to stir shit, create threads that represent your actual feelings and opinions.
Note: If your actual feelings and opinions are just to stir shit, that doesn't count and you will be banned. Obviously, there are gray areas, but most of the users and staff are intelligent enough to determine where these threads and posts fall under.
