An XSS vulnerability report was made via Open Bug Bounty, which was fixed, confirmed and a reward was made.
The reporter has marked the issue was resolved. They have further offered to remove the vulnerability from the Open Bug Bounty archive.
Being unfamiliar with Open Bug Bounty, I'm not sure if this is a good or a bad thing. The vulnerability was ethically reported in the open, so the fact that there was a report is already on the public record. The only reason I can think of to remove it is reputation protection, and even then it doesn't seem like a very strong reason.
My inclination is to leave it in the archive by default and that removal looks suspicious.
Is there a good reason to remove a report from the archive?
