If you're looking for a Techdomme, I have quite a bit of experience.
I'll lock up your phone. Not just parental controls. I have access to malware tools that are far more extreme than installing parental controls. Though I suppose I could do that too, if you get nervous thinking about all the possible capabilities the malware has.
About your computer: I'll take all your rights away so you can't even try to install or remove anything from your own PC, while I limit your screentime and monitor everything you do.
Contact me on twitter if you're ready to get locked up by a professional, not an 18 year old brat.
