Hmm... You didn't actually provide any evidence that Vercall (manger of the AVA_AREA bounty) and Leclerc2019 are the same person. However, it appears I already tagged an account
connected to Vercall, which is
Nicolas_park. Given the nature of the tag, which is that a bounty manager was enrolling multiple accounts in his campaign, it is likely that Vercall is indeed the same person as Nicolas_park. So I have tagged him under that premise.
