Very interesting idea. Glad you decided to make it transparent since I don’t think it will work otherwise.
I am not sure I think it will work as intended—in my opinion the state of political discourse on Lemmy is pretty bad right now, but that may reflect the broader state of politics in society more than our particular platform. If we want to create a truly positive space for political discussion, it might require more intervention than banning a small fraction of users. To use myself as an example, I try to be pleasant and constructive but I know I don’t always succeed. An analysis based on the content of comments could also be interesting to try. Or a kind of intermediate status of user, where comments require mod approval. That could be overly dependent on subjective mod opinions though.
Still, I think even if it doesn’t work, this is the type of experiment we need to elevate online discourse beyond the muck we see today.
