Because it's colluding topics. "break into your account" refers to a Coinbase account. "lack of regulation" refers to the Bitcoin methods. Using both of those in a sentence or quoting that sentence in another comment creates implied blame.

The original comment could be assumed to say two different things: 1. If Coinbase security was compromised, then Coinbase is accountable for the transfer of Bitcoin from op's account. 2. If the op 'allowed' access to his account through malware or unsecure API keys, then the op is accountable.

I believe the second assumption is what chasing was referring to. I should have been clearer in my questioning.

Edit: Actually, I shouldn't have even asked the question. I should have said what I said above instead of asking a leading question. My fault.
