Question about boosters.

Are there any legitimate challenger boosters?

I've had 2 claiming to be challenger - both got me demoted and ruined my mmr >_>?

As far as I know Im the only one verified by mods as ex rank 1 / current challenger. Suggest just checking peoples vouches though

Thanks , I feel like there needs to be some sort of verification process if they're claiming to be challenger... Really ruins people like you.
