I tried for a long time to get around it, but now when I hit a website like this just close the tab and don't bother anymore.
However, the undeniable reality is that accessing the website with a non-residential IP is a very, very strong indicator of sinister behaviour. Anyone that’s been in a position to operate one of these services will tell you that. For every…let’s call them ‘privacy-conscious’ user, there are 10 (or more) nefarious actors that present largely the same way. It’s easy to forget this as a user.
I’m all but certain that if Reddit or LinkedIn could differentiate, they would. But they can’t. That’s kinda the whole point.
And each one of these could potentially create thousands of accounts, and do 100x as many requests as a normal user would.
Even if only 1% of the people using your service are fraudsters, a normal user has at most a few accounts, while fraudsters may try to create thousands per day. This means that e.g. 90% of your signups are fraudulent, despite the population of fraudsters being extremely small.
