The only reason I didn't disable AdBlock for that site and explicitly decided to keep it is because of the way they asked for it. Had they said, "Dear visitor, we see you're using an ad blocker; please consider disabling it, because we really need the ad revenue to support the community", I'd even happily start clicking on the ads for them.
If you publish something and expect a compensation for it, say it up-front, and either restrict access to those who follow your chosen compensation route or stop whining. Publishing something on the Internet with open access is giving a gift to people. Giving something away and then guilt-tripping people into compensating you is antisocial behaviour, and if you ever tried to pull it off face to face, you'd be shunned by the community you're in.
