I've noticed that if you have less than 10 reputation, and want to insert an image in your profile "About me" section on a site which requires 10 reputation to embed images, you get this error:
Earn more than 10 reputation to post images.
Even when pressing on "Save and copy changes to all public communities" - same error.
However - when you go to a community where you have more than 10 reputation, and then insert an image and click on "Save and copy changed to all other communities" -
You don't get the error above, and now have the image you wanted to upload in your profile.
So, is it a bug? Intended? If it's intended, what is the purpose of blocking this if you can just update from another community?
In addition, if you have a temporary suspended account that is not allowed to change their profile description from one community, the user can still change their "About me" from a different community that they are not temporarily suspended on.
This is what you see if you're temporarily suspended and attempt to edit your profile:
While it does not let you edit on one specific community, you are still able to edit from another community you're not suspended on, and thus evade the block preventing you from editing your profile.
