VPN endpoints would not necessarily have low IP reputation. A VPN provider that allows its users to spam the internet is probably not a good one anyway. And besides, that would not inhibit registration, it would just make users fill out a form to apply so the server operator would have to go through and approve it.
Absolutely I use ad block. Ublock origin, plus a couple other privacy related extensions, plus browser configured with most privacy settings turned up all the way.
Most publishers seem to have no interest in giving me a good browsing experience, only in shoving as many ads as possible down my throat and violating my privacy as much as possible. So I have zero sympathy. I have sympathy for the smaller websites that then get locked as well, that wouldn’t otherwise have intrusive ads, but I am not going to subject myself to the larger ones just for their benefit.
Without ad block I have found a lot of websites almost totally unusable, or significantly more time wasting. Reddit is of course a big one, new Reddit without ad block is a total clusterfuck. YouTube is also pretty bad.
Thing is, I’m happy to pay. I’m looking forward to an era when I can do microtransactions in crypto to pay a website a couple pennies for content I like.
