CoinBase freezing accounts, is that real?

I saw a lot of posts in r/CoinBase about users complaining that CB is blocking their account without a reason, and I was wondering if is actually true or of they do it because of possible illicit activities going on, I have a ledger and a CB account, and I’m considering moving everything on my ledger to avoid this issue, I just DCA and use CB CC, no trading or anything, do I need to be concern or I’m just paranoid?

To be honest, I like Coinbase and I think they provide a good service, considering the possible issues with ledger, I’m no longer sure that using a cold storage is safer then using an exchange, but I might be wrong.
