Yeah, I've witnessed it in mikes server, lrk's server and the like. A noname joins, then I got high amounts of baud received and everyone looked like they were timing (I assumed the server crashed, but I was in it for a few min after), I tried to say something but apparently the noname thing kept inserting blank lines of text (no colon) rapidly so my text kept dissapearing with the blink of an eye. Didn't personally crash my server, though, since I cant host =P
