Well, he turned this into a matter of trust, and ironically, it would be interesting to see this as the standard.
I will bold a different part than you in Theymos' message, he flipped the script and made it so that you're a bit responsible for what you promote. Now, if you as a participant, can't trust the one you promote not to do anything shady, why promote them in the first place?
I'm pretty sure that if this rule would be applied to every service that has either broken the rules, exit scammed or just scammed a few users and so on, probably at least half of us would end up with at least one sig ban in a few years, but ....would this not be, at least from a moral point of view, justified?
Oh, and in this scenario I assume he talks about temp sig bans 1-3 months, not permanent otherwise...

let be real here.
We can never trust any website 100%
Can you trust dex.fo will not exit the market at any moment? I really think they are a real and good company, but you do not know the owner in person and you do not know the website for 10+ years
The truth is they can do bad things at any moment like many websites can, including my signature campaign casino Spinly.io
If we need to trust the website with our accounts or with our life, we will never use any signature
