I use sgtools too, mostly only for my winners ... because all reports that aren't for actual winners take up to 1 year to be handled :o(

The most multiaccount users aren't smart and have mostly very similar names, avatars, are friends at steam and such stuff.
But that don't count for all.

I work online mostly in the security and moderation section for groups, discords etc. and have a lot to do with "bad apples" and how to prevent that they enter groups/discords and/or don't do damage.
So i am mostly the man at the door that grant the access or kick^^

It is a good training to catch a higher ammount because i had many examples in the past (and learned from it/them) and use extern tools too, as example steamrep.com

And i have a lot of connections to different admins and can spread the word outside of sg (at sg is each word a risk for "calling out" -and to say nothing is difficult when you find someone with 38 not activated wins and such stuff....-)
