Recent events showed that not everyone know how to do that, so I will explain the procces or remind to do that for those who forgot. Its pretty easy and not that deep to understand yourself, but many people forget about possibilities of doing that.
Step 1.
Write in this label ganker’s name, its would work best with gank-based clans, just get the screenshot with their names or watch their videos to see their names.
Example:
Step 2.
Choose the first variant you get and click on it.
Step 3.
Click on “…” and then click “Block User”.
Step 4.
Repeat all 3 previous steps and block every potential splinter.
Edit: If someone is continuing teleporting to you through menu, then record a video, where you rejoin 3 times and the same guy teleports to you all these times. Then make a ticket on Vetex’s discord server and wait until the scum is banned.
