I actually enjoy the free speech of these forums. Some of the things said here may be considered offensive to some persons. Were I to be more serious about things such as race and ethnicity, as someone who has some jewish family members, I might take offense to maple's comments as well.
However, it is his right to spout garbage if he wants, just like it is Santa's right to call him out on spouting garbage on the forums. It is my right to classify it as garbage. It's other people's rights to troll the forums if they so choose.
The moderaters do not have the rights, inclination, or ability to moderate the forums. I agree with some of the other people here when they say its either completely free or its not. You have the ability and the right to avoid people or forum topics which offend you. It's that simple.
Santa, I sympathize with your being offended by racial slurs. However, as someone who's been verbally abused by you in game before, I find it strange to see you bring up something like this. However, it is your right to be offended. Theres nothing in the rules against being offended, or stating that you are offended.
What is agiainst the rules is spamming a pm inbox, specifically in this case, maple's. That is something the mods can handle, and something they will fix. It's not the language in the pms, its the rate of sending that constitutes spam. Had maple spammed you with racial slurs, he would have been told off also, but he didnt.
So your original complaint of the mods making this site a "fucking disgrace" is invalid I think. As the rules stand now, you are the one that violated them by spamming someone. There are no rules against flaming on the forum.
If you are of the opinion that it is wrong (which I assume most people are) then don't use them. Maple is apparantly not of that same opinion. Therefore, i suggest you avoid him in the future.
