I've been there. On a Discord I used to moderate, there were a few people like that who did not really break any rule, or not in an egregious enough manner to deserve a ban individually A rule was made for that situation: "If the effort and/or stress associated with moderating you regarding rules or general behavior becomes too much of an issue, we will remove you from the server.". That rule has been used a few time…
Oh, why didn't it strike me to put that rule in writing. Some users waste hours and hours of moderator time per week and it would be nice to have a written rule to point to for a timeout
On some level they are very hard working and if I banned them it would take longer to get my tasks completed. If they did 5% of the work that they do the low quality wouldn’t bother me because (1) a little of that diluted in the whole is OK and (2) the individuals would not come to my attention.
With some feedback some of those people might get better (I was always open to paying more for quality) but I also didn’t want to get into arguments with those folks.
