How Do They Know?

This is not a Strike support request. This is questions regarding the support I received and what methods are publicly available for such a decision.

I intended to make a wire purchase of BTC on the order of $5k with my Strike account, so I created a suppport request in their app to get a calculation or estimate of purchase and send fees that I would need to accommodate in my process. In response to that support request, something they would not answer here in the r/strikebtc reddit, they asked for details on a wallet I regularly send to for some time, looked like a KYC thing and I provided what was asked. After providing the target BTC wallet, they determined the wallet is associated with a scam AND have decided to close my account. Rather than just blindly accepting that they must know something I don't, I'd like to know more about how such a determination can be made just based on wallet address and transaction history.

So my first question is how do they determine ownership of a BTC wallet, enough to determine it is scam-related, given the anonymity of crypto wallets? Other than the transaction history which can be viewed in Blockchain Explorer by anyone, what resources are publicly available to make such a determination? Or is this just a calculated guess based on some AI-based pattern recognition?

If it truly is a scam, I'd like to know how to detect for myself in the future. I'm not asking about general scam detection methods. I am asking specifically about scam determination based solely on wallet address and transaction history. If there is no way to really know, closing my account seems more CYA than customer support.

I've used Strike for several years and have always been very pleased with their service and support. This time, the support leading up to this was not what I've come to expect from Strike. My initial questions were never answered, and I guess it doesn't matter now since they closed my account and of course refuse to reveal any specifics on why.

So if I can educate myself on scam wallet detection methods, that would be ideal. If what they have done by closing my account seems more CYA based on questions being asked by a customer than based on factual methods, that is a significantly different issue.
