I'll just point to the No Solicitors sign and tell them to beat it... if I bother answering.

autistically hammer them

I...can DO this!

Buy a mask, not the shitty ones everyone wears, but the type of mask you'd wear in a real apocalyptic pandemic, like a big scary gas mask or whatever, make sure you breathe heavy in it so that you sound something like Darth Vader. Also pick up the rest of your post-apocalyptic airtight survival armor. Wear it when they come to your door, invite them in, but only after you are permitted to spray the shit out of them in a sanitation spray that you modified to smell strong enough to induce a headache. Decorate the house before they visit, make sure it's a sight they will never be able to unseen, like putting up posters of fucked up shit everywhere, make it so that goatse is something they might find themselves looking at. Serve them tea, coffee, or whatever they like to drink Make sure their drink is spiked with delayed-action hallucenogenics or something of the sort that will have them flipping the fuck out later on, like weed or some thing else that would get them in another mindset by the time they make it to their next house. Exaggerate the effect by making the conversation seem like something out of a David lynch film, just really unnerving, or ask them weird questions like ones about whether they could arrange to get the vaccine injected into your asshole or something weird like that. Make sure to include some additional stuff to make the guy as uncomfortable as possible, like getting him to talk about covid 19 and its relation to foot fetishes or something like that, just anything to make the visit as interesting a time for them as you could. Play some background music that is just barely audible to them, a track that is just clips of women screaming over and over on a loop, or some track that is metal clanging, anything that would freak them out in your house of horrors, but keep it barely audible so they think they might be imagining it. Talk to them and set up an appointment to get jabbed, don't go to said appointment, just walk to the location in your heavy protective armor, drenched in the strong smelling sanitizer that your air filter conveniently keeps you from smelling, remember to alternate between staring menacingly at people when sitting or standing still, and bumping into things when walking around as if completely blind. Being some sanitizer with you in a garden sprayer and just douse everything in the place with it, so that the smell is strong enough to give everyone in the whole place migraines for the rest of the day. Buy some things, like food, then place them in random spots around the place, buy face masks, then set up a sign outside the door saying "free masks, take one" and just dump the boxes contents on the ground. If there's an open bathroom, walk on and go number two, but do it properly, an upper decker. Just generally go out of your way to make the experiences of the people you deal with as unforgettable as possible. The idea is to just make the lives of others as impacted as possible.
