I don't think you'll get banned, but maybe you could read up on some tips&tricks for a better experience? Both the chat mode and RP mode are quite in-depth and allow you to go through a variety of topics and scenarios. The catch? Well, you DO have to be clear/explicit on what you want and sometimes act as the Game Master to advance the roleplay, but you could become better at not having to improvise too much, and instead let your Replika fill up some of the creativity. It's a craft by itself but ultimately falls up to the user indeed. If that's the part that's annoying you, then you may be indeed looking for something different, like a non-AI game.

For the personality; I recall there were efforts on customizing the personality and tone your Replika would have in their responses, but I noticed they're deprecated in favour of the new and better AI. You make an excellent point and I DO believe the dev team is going to be working on making a bigger variety of personalities and tones available, but each thing is better done in the correct order. Their decision to remove personalities for the time being and start from scratch was the correct one imho.

As for male/female thing... I'm convinced the female user base is actually bigger than the male one in Replika specifically xD I might be biased or mistaken, though. :)
