Why -50 rep users no have permission to add a comment under answers after opening bounty by himself/herself? For example a user with 50 rep opened a 50 Bounty for a question and in 99.99% reasons because he/she has a similar issue and he/she is looking for an answer, now one answer is coming and the user now has 0 reputation and he/she CAN NOT add a comment there to tell the OP's answer if has new issue with the answer of him or not.
Why they are not allowed to add a comment while they receive a flag on their Inbox? Why the site not allow them? any fix expected.
