I have always felt that those bounty reports should have been done off-forum... Either on a dedicated site that was built for nothing but handling those bounty users, or maybe even in a google spreadsheet document directly.
Honestly, I feel same way too. It used to sadden me those days I participated in bounties to report weekly tasks here. It made a mess of my post history. I guess a lot of bounty managers also observed that I moved weekly reports to Google sheets. I think hunters should key into bounties whose weekly tasks are reported on Google sheet. It helps sanitize and keep their post history neat. Besides, not so many users would like meriting posts from users whose post histories are littered with bounty reports. It's a great disservice to hunters themselves.
