Careful with that, Humble has gone a bit mad in last few months and randomly seem to use the ban hammer for that.

Doesn't seem to be any specific thing that triggers it, humble just seem to be throwing the ban hammer around randomly when you give away too many games from the bundles.
Yeah, I know about that. I don't use gift links, and I claim all the keys and store them in a spreadsheet. Also got all the Trove games stored on a spare drive. A ban won't matter much as AFAIK they can't revoke keys.
