Someone has been suggesting a lot of edits regarding simply removing "thanks in advance" from the post. Should I accept or reject? I've always accepted, but I am not sure if I did the right thing.
Here is some guidance from Meta Stack Exchange (posted mainly with Stack Overflow in mind, but relevant here as well):
All you did was remove
thanksfrom posts, leaving other problems in place. Such edits are too minor and clog up the queue.
When making an edit suggestion, please improve the whole post, and not only remove the 'thank you'.
Generally, count on edit suggestions that only touch one small aspect to be rejected. Note that the too minor rejection reason states this unequivocally:
This edit is too minor; suggested edits should be substantive improvements addressing multiple issues in the post.
Users with editing rights (more than 2000 reputation) can edit "thanks" out without the hassle of the suggested edits queue. The point is that we don't want to burden the queue with small trivial edits and waste reviewers' time.
