I am facing the following decision:
1) We can remove a user that violated our rules in the comment section from commenting further. It would be the easiest way of implementing it. I just see the problem that we exclude the user from a discussion without banning him. Our systems and of course also our moderators do make mistakes so I am a little bit scared to do that and to destroy discussions. Also for one minor rule violation it would be quite harsh to block a user from commenting for good...
The good side would be that trolls etc wouldn't be able to continue breaking the rules in the particular thread they chose to do it and try to behave better in the next thread they want to participate in.
2) If we just remove his/her reply we need to write a little bit more code and in this case I fear that the trolling won't stop until we actively ban the user. Here a user could still take part and defend his/her stance and help to create a good discussion in the best case. In the worst case the user can keep trolling/abusing until a mod steps in.
I honestly know of no community that did the 1) approach so I am reluctant to do this.
One of the problems is that I don't have enough information about what could happen in either approach (especially Nr1) and also not the data to look into it. This is why I would like to have some input on what dynamics both could lead to.
The next is that I don't really know what the goal is here. I mean stop abuse in comment sections is one of course. But also enable users to have good, meaningful and also controversial discussions.
