Interrupting bots with trades is also not a good idea as a lot of them are being monitored and they can/will file reports for harassment if they notice you doing it. Heck, even if they just scroll back through their chat log when they wake up and notice it they'll still have enough evidence to get a GM on your case.

I feel like a lot of them specifically avoid turning on Do Not Disturb status just so they can do this, since they have to know they're pissing people off.
