Probably for online, similarly one post would be allowed for each individual human approval, unless you ad the bot disclaimer.
If I made custom keyboards with just a few choices each, I think I could probably handle half a dozen without any problems.
And if I'm literally just always telling the bot "okay, go" with 1 button, I think I could handle dozens.
Who would those bots be? wccrawford1, wccrawford2, wccrawford3? That would not pretend to be anything other than bots or clone accounts.
If on the other hand your bots would be "Brock Samson", "Joey America" and "Chip Dipsby", etc. That would clearly be non-humans pretending to be humans, regardless of you tripping the first/last domino piece.
If I had live people answering, but their names were randomized, would that not be okay?
I honestly don't see any real difference between naming the bots like that. Yes, some people will be less likely to think they're bots if they're all named differently. But the vast majority of people will not notice if they get contacted by several different employees/bots all named Brock Samson. Most people won't even talk to more than 1 employee in a short timeframe to even have a chance to know there was a difference.
