>>704471appeal the ban
the mods are suprisingly fair about these things
unless you have a dynamic ip
delete all cookies every time you restart your pc
stop accessing 4chan frrom multiple devices from the same wifi
atleast thats what i did back when i kept getting range-banned
i think its a failsafe to combat bot farms operating on a single ip or something
they should probably white-list your ip if you're persistent enough
it took me 5 bans /appeals over the first few weeks till it fixed itself
be polite and explain yourself in the appeal note and they'll try their best to help
don't fall for the "jannies bad" meme they are nice people
