I wonder if we all did this, how many tips we'd get.
I've just started putting a
BTC tip address on my craigslist free stuff ads (where I see stuff dumped in the public right-of-way, post a picture, geolocation, time last seen, what was left the last time I saw it).
Only the {noun(s)} is/are left.
Please MMS pic of what you took to {cell number} so I can edit/delete this ad.
Last checked: {time} on {day of the week}
I post dump sites around {area} as a public service, bitcoin tips welcome: {BTC address}
Probably unethical to post your own possessions for free and ask for a tip, but if you post a bunch of dump sites regularly, people could cross-ref your ads and not know which dump was yours.
local rules: don't quote the OP (as this is a Work in Progress) & don't post nonsense just to boost your post count for ad campaigns
