They should be way more explicit, as the referenced
Terms of Service doesn’t really detail explicitly the prohibition trades, except for what their chapter on prohibitions of use dictates, which I find vague, leaving the reader needing to jump to external lists to try to interpret his personal circumstances:
Decapitalized (for being painful to the naked eye) quote from their TOS:
d. Prohibition of Use
By accessing and using binance services, you represent and warrant that you have not been included in any trade embargoes or economic sanctions list (such as the united nations security council sanctions list), the list of specially designated nationals maintained by ofac (the office of foreign assets control of the u.s. department of the treasury), or the denied persons or entity list of the u.s. department of commerce. Binance reserves the right to choose markets and jurisdictions to conduct business, and may restrict or refuse, in its discretion, the provision of binance services in certain countries or regions.
Since you have seemingly received just a warning, and not a de facto sanction, it’s possible that they have linked one of your inbound/outbound TXs with someone that fall into the above vague categorization, but either through probabilistic heuristics, or a few step backs in the chain. I’m not sure if the message would be such as the one displayed if there was a complete certainty.
As suggested, I’d reach out to their support to clarify the case, and see how they’ve reached their conclusion.
