It is some one with a password. It a real hacker got in he would not just send a message or two.. I have looked at the time stamp of the post and the site logs. I have an idea of who it is. I also did notice that the "O" person has not used any bad language or do anything malicious, so at this point it is not that big a deal..
It does seem like a waste when they could be usefull and helping with the probes, The "O" person(s) seem smart. So maybe it was one of those wild ideas they acted on.
