Hold onto your panties
I used a Zoom H2 mic and some pre-amps and used to throw concerts into international music rooms. I should have thought to do something like you did. I did have a Digitech delay pedal (one of their first I believe). The most annoying thing I ever did was to this guy who was trolling all the rooms on mic and gathering a small following as he went. He was notorious for also using flooders to boot everyone out of a room that stepped on his ego. I recall programming some bots to a flooder which targeted him and his alts. He got booted out enough times that he gave up and had to take his e-crowd elsewhere to worship him.Wow, Yahoo Chat. That brings me back.
Used to go into the Karaoke rooms with my Mic piped through my guitar pedals and use my DDS3 Stomp pedal (Digital delay) and cause havok. They'd either confusingly clap at the end or go mental. I'd sing a song and just keep turning the dials, I reckon they thought their connection was busted. Was very funny and must be nearly 20 years ago. Eventually they got angry at my dulcet experimental tones. (mostly loops over loops).
Trent Reznor and Mike Patton had nothing on me.
