How should I politely make myself known to the person requesting a game?

The problem is related to Tallinn92. If I answer his request to play no, then a barrage of requests comes out like a machine gun relentlessly. "No" probably means no and I answer that too many times without success, finally I have to close my game table. And he still has an Estonian flag next to his username. I don't want to chat with him either.
Sincerely, Ants Pihlak.

Well, put a rating limit on the table so he can't join ;).

Of course, this functionality would also be useful here: Black List

Thank you.
I have no desire or inclination to punish anyone for seemingly trivial matters. But isn't it possible that someone, after failing, cannot use the court to express their desire for the same case again? Just as it is not possible to undo moves?
This is an ignorant opinion, of course, but no is still no.
Be healthy!

Check the box next to Don't want challenges and invite players yourself.
Of course, not everyone wants to come play, but you can still get some.
When creating a game table, you can choose the rating range or maximum rating you want to play with.
For example, www.lichess.org organizes tournaments where there is a maximum rating that can be reached at the tournament.

Thanks again. As an old person, I will continue calmly in the old spirit and simply scare away the overly pushy with "appropriate handwriting". I think the options are good for lower-rated players, so that they can choose their own opponents. They seem to have the interests of learning in the foreground. I am also the same kind of chooser, although time is probably running out soon. Ratings are a nice thing in general, but chess is beautiful just the way it is. However, certain people with high ratings seem to be looking for "leafy bugs" like butterflies in nature, because it would seem to be an easier way for them to increase or maintain their rating.
But as an old doctor, I wish you good health.
