Yeah that's why it's good to start a new reddit account every year and delete the old one. As well as VPN, regularly changing mac address on your router etc.
The mac address is layer 2 and no one other than your ISP knows it. Changing it does nothing for your privacy since your ISP knows it anyway.
a lot of cable companies will have you keep ip addresses for a very long time. The only way I've found to get a new one quickly (without taking my cable modem offline for many hours) is to swap the mac of the router in ddwrt (router firmware). That works "nearly instantly" as long as you reset your router and cable modem.
Fair enough. If I change the mac address of my router the ISP locks me out for a substantial amount of time, deffinately not an option.
Or if you're like me, Reddit will helpfully shadowban everything you ever wrote on your decade-plus account, while simultaneously claiming you can't use the appeals page because the account is still in good standing.
As a bonus, anything anybody ever wrote in response to me is gone too.
