I was going to suggest similar... ie get some 'S&M Escort Service' business cards printed out with her name, address, 'service' she was providing and put them up in the local telephone boxes with all the prossies cards.... but then I remembered that it's 2018 and I can hardly remember the last time I saw a telephone box on-street....
..and I guess that printed business cards for hookers went out with the Ark since everything's available as an App these days.... Can you still buy Razzle?
Do you live directly above the person you are trying to annoy?
if so if you haven't already get laminate flooring but don't put the insulation/padding stuff under it and make it a bit loose then get a 3 year old to spend all weekend every weekend to run up and down non stop for 15-18 hours a day
Also if they have a dedicated parking space get random people to park in the space every time they go out, you could also try to get everyone in the building as soon as there is the slightest thing that goes wrong that the landlord is responsible for knocking on her door and complaining and saying well your dad is the landlord who else would we complain too
dicking with any automatic smoke detectors so that the test beep goes off every 20 seconds is for winners too
I've just got rid of my van, however I could put one up in the trailer (it's the back end of a Mk4 escort van) though for advertising purposes maybe calling it 'vagrant in a van' and 'tramp in a trailer' would work? along with 'bum in a bus*' and to go a bit more septic 'wino in a winnebago'
edited to add - I forgot about 'total and utter bellsniffing cockjuggling thundercunt in an Audi - nothing to do with tramps, just that so many fuckweasels end up driving audis'
*although that could be taken (literally) the wrong way
