I just rejected about 10 edits from the same user who were just retagging questions from 3 month to 1 year ago. I accepted the first few, then realised it was the same user, giving the same reason for each edit. The tags before were already appropriate. He added tags which could be added, but this is not really necessary. I think this is just ridiculous attempt to gain reputation.
The reason I did this was that many of these questions have answers and retagging them would just clog up question feed. I want to ask:
Did I do the right thing here?
is there sort of warning you can give people requesting users not to do this or report to moderators to give them a warning?
