I think we have convicted whoever sent the PM without the benefit of any evidence. WAS the PM rude and malicious, or just truthfully blunt? Was the PM sent to avoid detection of being a dick, or to try and avoid everyone jumping on the bandwagon? Everyone seems content to call the sender a douche without even knowing what was written.
I suggest that if the OP finds the PM malicious or hateful they should report it so the mods can deal with the sender. If not, This post only serves to stir up a riot over nothing, with people jumping on the "bash the sender" bandwagon without even knowing what was said.
If the PM was not bad enough to report, or didnt bother the OP enough to report, i maintain that it wasn't important enough to warrant this much discussion. Im sure whoever sent it is getting a pretty good chuckle put of this thread. It sure got them plenty of anonymous attention.
