[2020] Is hiding all game to not end the game bannable?

Basically, something like this can be reportable if you can prove they've done nothing in the game but hide and the game did not progress (e.g. no gens were finished etc.). This is when it can become a bannable offense for holding the game hostage.

For that report them in the game and attach additional evidence in the report or send it to support: https://support.deadbydaylight.com
