Maybe explain carefully that you feel you are being abused and this is distracting you from learning or participating. Feel free to link to this post.
What needs to happen here is for the moderator to step in and say … “listen, X please stop replying and liking Nate’s post or I am going to have to kick you out of the course”
I get you want the tooling here to “invisible” a user, and turn Discourse into a site where user X does not exist to you. But if something toxic is afoot it has to be handled, you are presumably paying money to this educational institute, they should offer you some protections.
I have been on the fence for years on even supporting ignore/mute cause I worry it can just let toxicity fester. @codinghorror got swayed to implement it based on real world feedback.
I guess we could implement the error “Sorry you can not like this post cause Nate is ignoring you” and “Sorry you are not allowed to reply directly to Nate cause Nate is ignoring you”, but this does change the dynamics of the feature quite a bit, this is certainly not something we will be changing tomorrow.
