Make sure you have a complicated password that you don't use elsewhere.
Consider using a unique username that is unrelated to your email and other accounts you own.
Consider changing your password periodically.
Don't reuse your password on other sites.
I know this from personal experience...
My account on bitcointalk was compromised and they changed the email address so I can't reset it! Just yesterday I messaged the admin Cyrus with a signed message from the first bitcoin address I posted on the account. I still haven't heard back from Cyrus, but I hope he sees my message soon. The person who took over my account doesn't seem to speak English as a first language, and even features a different identity now...he's spamming for some bounty campaigns, but he left all my old posts unaltered. Luckily I still own the bitcoin address and private keys posted by my account to sign and verify a message using that. It still sucks though. You don't want this to happen to you. I don't think I even got an email saying my account's email and other things had changed, at least I didn't see it. So again:
Make sure you have a complicated password that you don't use elsewhere.

Consider changing your password periodically.
Don't reuse your password on other sites.^^>^^^^>^^^^^^>^^^>^^^^>^^^^^>^>^^^^>^^>
