Personally I find steemit to be more politically correct than even Facebook. At least with facebook you can delete your account. Here on steemit everything you do or say is on the blockchain forever hence you need to be wary of what you say. Unfortunately most people are here mainly for the financial rewards which is dangerous as you may post things that you shouldn't. Regular spammers should be penalized through flagging as it is a negative for their reputation score which has a knock on effect, however I believe bots are are not always correct and can damage your reputation quickly. A case of found guilty before you can defend yourself.
