Why do exchanges keep suspending my accounts?

For example. Crypto.com shut my account down and I couldn’t even get into the app for MONTHS they said it was due to fraudulent bank activity. I emailed them for months but kept getting the same response from a different agent. It was ridiculous and than one day my account was restored.

Now, currently on Coinbase my account is suspended for the same thing due to fraudulent activity. All I do is buy some crypto here and there with my chime debit card. Not sure why there is fraudulent activity. I live check to check like a lot of people. Not doing any thing shady at all. Both support teams are useless in explaining why this keeps happening. And my bank doesn’t know why either.
