Bots with random names

[Canadane]

Pretty common. Gil-farming bots were always there. Best to ignore them.

This, except don't ignore them, report them!
Catch at least one of their names and you should be fine. Let the report show there was many of them and I'm sure the GM handling it will know what to do. ...hopefully.

If you can target one of them, you can use /e <t> so you can have a record of their name in your chat log for later reporting.
