My flagging privilege was probably removed with the following error message:
Too many of your recent flags have been declined - please review them instead of flagging this post!
Although my flagging stats were the following:
182 moderator attention flags 45 waiting for review 109 deemed helpful 5 declined 23 disputed
I initiated a dispute, partially about the revoking of my privilege, and about another questions as well. You can see that in my history here on MSO: https://meta.stackoverflow.com/users/244746/peter-horvath?tab=questions
After that I got my flagging ability back, without any explanation.
It enabled me to flag the following post as "very low quality": https://stackoverflow.com/questions/23013623/how-can-i-add-my-site-to-java
This flag has got a "helpful" decision from the moderators.
But currently I can't flag again.
What is going on?
P.s. Please don't try to redirect me to my flag summary, I copy-pasted my flagging statistics from there.
