Cannot change profile picture, cannot even ask for support!

Hi,

I know it says we should use the feedback form when we need support, but unfortunately it doesn't work either.

I was trying to send this message:

Trying to change my profile picture doesn't work. (The current one doesn't display well on this site so I was trying to put up another one.) I either get a white screen or a message "OK (not really, your are acting as a spammer)" which is not clear because in what way is changing your profile picture spamming???

...just to be greated with the same message "OK (not really, your are acting as a spammer)" - what the...? like, I literally just opened my account, trying to set up my profile, haven't sent any especially high number of requests or anything, it's the second profile picture I ever uploaded on this site and the first feedback I am trying to submit. In what world is that spamming?

Please advise how to solve this problem.

Thanks!

I was able to do it in a private browser window now, but changing the profile picture still doesn't work. The "clear" checkbox does nothing, and selecting a new image ends up on a white page, and in the devtools I see the error was net::ERR_HTTP2_PROTOCOL_ERROR.
