I understand that "thank you" is considered noise on main sites and should be edited out. On meta sites, rules tend to be a little different though (e.g., discussions and opinions are allowed, etc.) so I was wondering if "thank you" is generally acceptable on meta sites (at least when it's not just a generic "thank you"/"thanks in advance" comment) or if it should still be edited out. After all, we have some posts dedicated entirely to thanking a user or a group of users.

The incident that made me decide to ask about that was in this question¹ where the author decided to thank the community for their collaborative effort at the end of the post:

I would like to thank everyone who helped in creating this reference.

But it was edited out recently as noise (see: revisions). I was going to rollback the edit but I thought I should first check if there's general consensus about situations like this. I didn't find any posts where this has been discussed, so I'm asking you: what do you think?

• "Thank you" in meta posts should always be edited out as noise?
• They are generally acceptable and should be left alone?
• They should only be edited out sometimes? Explain.

¹ _{This is just an example; please don't make it about that specific question.}
