Recently a lot of suggestions were added for different situations on the site. For instance if I write a question and add words like 'problem' I get an error saying I should not use this word in a question title.
Still from time to time it happens to me that I have an answer with zero upvotes and that is not accepted but it gets a comment like
Thanks a ton you saved my day! or
I can not express my gratitude. I could leave a comment like
you may as well consider upvoting/accepting the answer, but I feel somewhat awkward to write such comments.
I would like to suggest that whenever a user writes
thank you or something of a sort in a comment, a suggestion comes out that he/she should maybe upvote the answer/comment he/she is thankful about. This of course should not be an error because it will not be appropriate every time but still a mild suggestion will be helpful.
