Question about the Bounty System

While in Warmode I hunt down Gold farming bots, However I have a question regarding ‘When’ and ‘Why’ you end up with the Bounty Debuff removing your ability to fly.

What triggers it? At first, I was under the assumption that a high enough killstreak while the Buff ‘Alliance Assassin’ was active, However that doesnt seem to be the case, as occasionally when I ‘do’ die, I’ll start the farm over, and after the first kill, I’ll have the ‘Bounty’ Debuff placed on me immediately after, As well is there any way to remove the ‘Bounty’ while keeping the Assassin damage boost?
