Here's an idea:
Every time someone asks for /pol/ to be deleted, ban them from all boards except for /pol/.
That way, if it's actually /pol/ false flagging, they have to go back to their board, or if it's a Tumblr tard, they have to either go to /pol/ and argue their points with them or fuck off.
I have a better idea
Ban /pol/ posters from the rest if the site.
That way real crossboarders won't be able to shit the rest of the site, and false accusations wouldn't be possible anymore. It's a win win situation.
/pol/ is a board of peace. Sure, sometimes anon shitposts on other boards with /pol/ related material, but they're either not from /pol/ (since true /pol/acks keep their political posting on /pol/ where it belongs) or the occasional bad apple triggered by 4chan's rampant /pol/phobia - just look at how much /pol/ is blamed for on /qa/, for example.
So don't be a /pol/phobic bigot and think twice before throwing around such baseless and hurtful accusations.
Thank you for your time.
No you didn't. You mentioned false accusations wouldn't happen, you said nothing of what happens after that fact or what the hypothetical plan would be if your idea did absolutely nothing to curb what you're complaining about.
It's logical to assume that if banning /pol/ posters from interacting with the rest of the site doesn't stop the spread of their ideas or sentiments then you're only left with banning people for saying shit you don't like.
Why? I'm not the one advocating for bans because people are espousing politics I don't like.
