It is generally (always) a good idea to not reuse passwords across multiple sites, especially if you are using the same email/username as well. There are a number of instances in which sites have been hacked and the DB containing the (either hashed or plaintext) passwords have been leaked, plus there is the risk that the owner (or other insider) is acting maliciously and will attempt to hack your accounts at other sites.
Thanks for advice, I took it lightly before by being lazy, but that's the only weak thing I had, my other sites and emails are F2A and different passwords.
