Yo netceetizens, my neighbour is on some racist crazy shit. What should I do? (It's a TL;DR thread, deal with it.)

lmfao, nah, not anything like that. More thought out shit is needed for this. I was thinking more in the lanes of the gay community being generous with condoms when certain firms knows about you having a party and gives you a shitload for it. A friend got like 500 condoms for a new years eve party just because they sent a mail and asked a firm for it (jokingly). If I could somehow do something like that (his mailbox will be flooded) then we could be on to something. Just small things that annoys him and that I can complain to the landlord for blaming me on (if he does) etc. so he gets in a bad light. It can't be obvious it's me either.
