I’d love to do this but not even scammers will friend me on Steam 😢

My technique is to soak a papertowel in isopropyl and press it onto the sticker for a minute or so, which dissolves the adhesive enough that if you’re careful you can peel up a corner and then gently and slowly pull at roughly a 45 degree angle to get it off intact, then use said isopropyl laden towel to clean off any remaining adhesive.

Even that is a pretty optimistic outlook, it’s more like a slightly slower increase in suffering over time rather than any sort of net decrease as a reward.
