How exactly where you hacked? If it was through an email compromise, then you will have to protect your address; use security conscious mail services, like protonmail, do not expose your personal details and do not use the same address for multiple platforms, so a breach in one does not result in a breach in all.

Also, take all precautionary measures:
• Use a strong password and change it from time to time.
• Do not log in over unsecured WiFi
• Check for phishing sites, some would use the forum's interface and try to trick visitors into entering their login details.

Is the account still active? If yes, try restoring the password using secret question. This would lock the account and prevent the hacker from causing more damage.
If you don't remember the secret question, you can request that DT members tag the account, but you'll have to prove that it is yours for that to happen. The follow the instructions in the link above.
