Verifying challenger

So how is this done by the rules?

You could just try to message "Lilouus" ( probably the most trusted booster here ) and ask him to play 1 or 2 games with you so he can give u feedback in your thread.

I give you 10 accounts, you boost them to Diam I and I will vouch for you! Jk ofc, try with Lilouus or one of the other trusted challenger boosters.
