[Ourotica]

We're in a similar place in terms of restrictions on promotion -- we can't advertise on any of the major platforms, at all, ever.

One thing that has worked for us is directly reaching out to community groups or (and I hate that I'm about to use this word) influencers. I'm sure there are plenty of sober / in-recovery people out there with large followings and/or community connections who believe in your cause.

It can be tough, because people who dive bomb into a community for the sake of self-promotion are gross and deserve to be shunned, but there's a balance there where you're actively participating, and helping, and also telling people about the thing you're doing to help.
