exactly. the good answer may just be start small. If the OP had actually posed a task for which the bounty was a reward and if the task wasn't too onerous for the 1000 sats, perhaps some people would take them up on it. SN shows when a bounty is paid, so we'd have a small data point if this bounty was successfully paid out.

Of course, the OP could create a second account and pay the bounty to himself, but SN takes a sybill fee, so this would be a costly adventure. I'm no web of trust expert, but it often feels to me like it makes the time factor too implicit. Even if a person is not known to you or to anyone you know, if you have a way of verifying their track record, this can be a very powerful means of building trust.
