I'm unsure as to the specifics, but I've encountered similar problems.

Reading these may shed some light, or at least explain depth of the darkness.

The problem is that the chat script identifies users by their name string, such as "H̪̬͚̲̥̠̗̻̿ͦͧ̂͟E͚̞͋͛ ͕͇̦̻͓̻̳́ͫ͌̆͌̽C̢̊ͯ͏̵̣͈̣̯̯͔O͚̲͓͎̟̳̱͐̊̈̽ͪ̓ͪ͞M͖͔̗̮̎̈́͑̏͡È̸̝̹̲̍ͦͤͦ̋̎̀͞ͅS̢̫̮͙̟̭̀̿͜", rather than their user id, if they just treated people as numbers, such as 26009167, the problem would have never occurred.
