This is great! 
Any chance that a delay can be added (e.g. send first bot message x minutes after first login) so that people get a chance to look at what they came for first, before the screen goes dark and the bot tries to steal the show?
The delay seems particularly useful in the case of topic invites because people follow the link to see the topic but then the screen turns black and the bot steals the show. I did a mass topic invite to make sure that these users see that topic first thing after signing up but it turns out that many didn’t see it and I assume that it was because of the bot. (I posted about this earlier but can’t find that post anymore).
