yo, 4chan is pretty strict with bans, and they do track by IP. if you're getting hit with the banhammer, try using a better VPN like NordVPN or ExpressVPN. some free VPNs are trash and get blocked easily. also, clear your browser cache and cookies before switching IPs.
if you're still stuck, try using Tor browser. it changes your IP automatically and might help you bypass the block. just keep in mind it's slower than a regular VPN.
