Bogus error message when trying to edit a post I just published

When I try to edit and save a post I published less than 5 minutes ago, I get this bogus error message:

(oh, seriously? You don't support copying and pasting images? Ok, let me save and upload the screenshot....................)

See the attached screenshot.

We have a lot of trolls and robots posting spam here and this is one of the defense lines.

it was set up my the forum admins yrs ago.

Sorry for the inconvenience is all I can say

It wont go away until you have 100 posts under your belt.
Nor is it a bogus message.
It is covered in a few other posts too found by a little reading.

@php4fan, express your dismay here where it has the potential to bring change...
