If I figure out someone is doing that, I'll never trust them again. I'll literally blacklist the site and if I see it posted here or anywhere else I'll point it out.

They should start charging money then. Return 402 Payment Required instead of a free HTML page. If they send me ads, I will delete them. I won't be losing even one second of sleep over the matter. I'd delete real life ads too if could get away with it.
