If ever you see chatroom posts disappear without the entire last 999 posts being wiped; or if ever you see your own ISP address, or other personal information, suddenly posted in the chatroom for all to see—-then it is almost definitely the work of Mr. Alan Angerbauer.
You should immediately report what you have seen to David Tseng at firstname.lastname@example.org, to Mr. Angerbauer's supervisor at [personal info removed]. (I assume our hacker sometimes invades our privacy from his workplace), and perhaps even to Mr. Angerbauer's local law enforcement.
Mr. Angerbauer uses a large variety of names in the chatroom; but a good sign that he is there could be that his girlfriend, whose registered chatroom name is "bee charmer," may also be there. And Mr. Angerbauer has taught her at least one of his tricks. Yesterday morning "bee charmer" erased a long portion of the chat which apparently didn't meet her liking. If anyone doubts this, they should simply e-mail email@example.com, asking that the chat transcript be reviewed.
David Tseng should take an immediate and serious interest in this, or else he should CLOSE THE CHATROOM.
This is not a joke. I encourage you all to be as careful as possible.
