First, I wouldn't have left the trade up for "a few days". Two days is my max that I'll leave an offer up for. Helps to avoid situations like this one and the other owner gets an email that the trade was offered and also and email that says you took it off the table. The other owner will offer it back to you if he's interested.
Secondly, it's not a new Yahoo rule. It's always been there that foul language will be removed, and they can suspend your account for the violation.
Lastly, what good does it do to post a profanity laced tirade? All it does is make you look uneducated since any child knows a bunch of cuss words. Make your point known in an adult manner and you won't have any problems with Yahoo deleting your posts.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
