Actually, it is my belief that making contact was not a good idea.,
Now they know they have a live person and perhaps attempt to exploit you even further.
As far as I know, the thread cannot be hidden. And hiding the thread would serve very little purpose with respect to other' truly trying to help you. However that is just my opinion as I understand Forum rules and practices so will defer further answers to others who know more about such things.
And, depending on where you live (not asking) there may be many other factors involved. Do you, for exampe, trust your ISP? Are they secure and working to block attempts to hack into customer accounts and services.
Someone may have gotten your information before you secured and/or disconnected wireless. Use a strong passwordl for your router or modem/router. Change the password on a regular basis and do not give the password to anyone. Make sure the router is secure so no one can factory reset the router.
Close as many accounts as possible. Change passwords and take other measures to accounts that you must continue to use. Continually monitor those accounts - especially fianancial, health, education, and health accounts.
If the person or persons hacking you discover that there is nothing to be gained by hacking you then they will move to other easier and more profitable targets.
Should they respond to your DM do not respond back, Change as much as you can, increase security, and likely they will move on.
Just my personal thoughts on the matter. I do not speak for Tom's Hardware.
