Change your password and send apologies...

Set things to normal again by posting an apology and saying that it was hacked and you are not responsible for all that happened, specially to that person who was a victim of the hacker.

If you can get in, change your password immediately, to something you can remember, and don't give it to ANYONE, ANYTIME, ANYWHERE, for ANY REASON. Make it a GOOD password (non-dictionary words, upper and lower, numeric and special characters, 8 or more characters. No 'keyboard patterns' or number only type passwords).

Send apologies, and post you have been hacked so everyone can see it. Send personal direct apologies to whomever got the brunt of the 'bad stuff'.

Change your passwords every couple of months. Don't keep it written down in your room, or near your computer.
