Yes, I made someone angry so they managed to get into my website. Unfortunately, silly me used the same password on my email as a password used on my website so they got into my email and my other accounts.
I was quite happy though when Omni of HF provided the IP address of the hacker because he had gone on HF boasting about hacking my site (not knowing that I was also a member on HF at the time - and friends with Omni).
My old site was hacked a couple times due to an admin's credentials being compromised (not mine). Fortunately, the site was already pretty much dead at the time.
Nope, can't say that it has. Though, Wordpress tells me when people try to hack my admin account. I use super complex passwords for all of my accounts and each account has a different one.
