In this case, asking your provider to change your IP (some providers have options for that, for exaple mine change my IP whenever I restart the rooter), sharing the phone network (another network = another IP) or using a VPN (use an IP from the VPN server instead of yours) are potential solutions
(but yeah, banning an IP also means that nobody at your home will be able to access Reddit, that’s not any kind of ban, be careful with your new account, don’t do too much shit if you don’t want to also loose it)
