Just expanding: users who donate via Blockmetrics are still being served Blockmetrics code, but since they've donated they won't be bugged again. Blockmetrics doesn't tell me who donated - could be anyone, even not logged in users.
We do offer a subscription service, which we started at $60/year. Very few used it. We dropped to $25/year and we saw quite a few new subscriptions, but still hundred in a hundred thousand strong membership.
Subscriptions give very fast page loads because the ad scripts aren't even sent down the line, so the html is smaller, and pages render faster, even if someone is already using adblock.
However there are those who want everything for free. Some say "I already pay my Internet service who should I pay to read something now?" or "Why should I use my Internet service to show ads for your benefit?"
These people obviously think everything is free - servers, capacity, CDNs, database, etc, etc. I wonder if they would go a day without receiving their salary...
