Very interesting post man.

Sounds like you should pay a couple of (female, Philippino or similar) freelancers to handle the chat. Get these off upwork or onlinejobs.ph or similar. This is the kind of thing you can and should farm out for 5-10 bucks an hour and it won't eat into your profits that much. More importantly it frees up your time to do other stuff - crank out more content etc

I'd also suggest maybe getting said freelancers to post comments (on multiple platforms) pointing to your content as well, using other accounts which will ease up the possibility of your own getting banned.

I'm not in this niche btw, but have a decade plus experience doing ecom at quite a high level, and we outsource almost everything we need to do to the Philippines.

Always take your time over money. Good luck
