Just like with the transfer of /v/whoa to HaHaBird who appeared to have bought or used bots to qualify for the sub transfer, it looks like Flying_Mouse may have used the same tactic to get /v/WhatCouldGoWrong transferred to himself.
Mouse's comments in the sub (leading up to his subverse request) all had precisely 3 or 4 upvoats for each individual comment.
Here are archived links of some of his comment pages revealing these suspicious comment points:
/v/WhatCouldGoWrong was a historically 'dead' sub with little to no commenting and any comments typically got 0 or 1 point. So for Mouse to receive these precise number of upvoats for every single comment is highly suspect.
He requested the sub 15 days ago
He was granted the sub 8 days ago
One could argue that bringing content to an otherwise dead sub is a good thing (and it is if done honestly) but the fact that he may have gone about the transfer illicitly and co-mods /v/WhatCouldGoWrong with 'user' ReadMe whose bio reads "Add me as mod of your sub for posting" looks like a coordinated power grab rather than acting in a community spirit.
What's even more suspect is that ReadMe and Flying_Mouse have both started posting in /v/scifi together and I wouldn't be surprised if either one of them made a subverse request for that sub soon. ReadMe has been especially aggressively posting in /v/scifi.
On top of all this, ReadMe co-mods /v/whoa with HaHaBird (who I mention at the top of this post). ReadMe does seem to want to expand his ownership of subs considering how quick he's been to contact mods for co-modship.
Here are examples of ReadMe requesting co-modship:

Edit: And now Flying_Mouse has deleted this post in /v/WhatCouldGoWrong which asks the WCGW community about this post.
