This guy is bumping their bounty thread without caring forum rules.
https://bitcointalk.org/index.php?action=profile;u=2097609If you can look his post history he didn't post anything interesting and just making one word multiple post for bumping their bounty thread. I don't know how to report that kind of bumping spam?
multiple bumps within 24 hours (roughly) are not allowed; whenever I see something similar I usually just report stating this rule. for this instance, I would go with something along the lines of 'spamming multiple bump posts all within a small timeframe, delete posts + temp ban'
