I buikt a minimal bot some time ago on reddit. It was very simple. It reacted with predefined response when it detected specific terms.
While it was mostly made for a joke. I was surprised how efficient this was. I received mostly positive return as well as some infuriating responses. Still this was effective.
The current platform appears to actively prefer the russian bot presence. So an option might be to provide a FOSS bot maker that anyone could easily use that will also have the property to be easy to not be detected immediately as a bot.
Then these bots should both counter russian bots and promote this bot creation tool or even platform (bit a platform would certainly be easier to detect and block).
But by doing so, the dead Internet is closer than ever.

See stack.yaml file for the env var to set. If you run it it should start a web interface. And you can create new bots from there.
