During most days they automatically post on average every 2-3 hours. When they post a question it is usually 3 messages back to back within 5 minutes. The first announces the next round is about to begin. The second is the question itself and is timed. The third announces who won sats. Also, if someone requests another question, the bots can post more often but this isn't happening much lately. Only other time posts happen more often is if myself (@son_of_vin) is testing updates or reported errors. Thanks!
