Forum and ingame bans work in tandem?

Many of you know i've been a good boy during my time here, generally bringing a positive vibes and never involving myself in squabbles that may lead to any form of punishment, excluding one misunderstanding that i had a 24hr forum ban for awhile back... 😃

So i haven't played for 4-5 day and logged in earlier to be greeted with 

My initial thought was my account had been compromised but after reading the email i'm already 48 into a 72 hr ban.

If the game wasn't so broken i might have noticed it sooner.. 😛

I can't post what i said as i was replying to someone being toxic in a very warm, kind and unbannable manner.. 👿  but apart from a sense of pride and accomplishment being my first game ban in my 20+ year history playing fps games on PC (i know you console players have the dictatorship boot that comes down frequently) i'm left curious to know if the forum ban i had for 24hrs and now 48hrs ingame are stacked or are they seperate? ie if i didn't have a previous forum ban would my punishment have only been for 24hrs?

Also, if you're aware what the next one is (7 days or something) let me know as i like to live on the edge. 🥳
