I don't know what the solution is here.

One of my sites enjoys a ridiculous number of fraudsters trying to make purchases, many - but very much not all - from the tor network.

The easy solution is to punish everyone and ban tor exit nodes from access, and woo, a significant reduction in my fraud rate.

The way I justify this to myself is that the site only accepts payment via PayPal and/or credit cards, and paying with those in itself gives up a good amount of privacy.

For sites that don't make a profit and have to use unpaid time to clean up the mess from some tor nodes, I really don't know what the solution is.

It definitely sucks for legitimate users.

Edit: one more difficulty is that I don't know if I was targeted by one or two lazy-yet-determined fraudsters who only use tor, and so make tor look worse than it is with their repeated attempts. No idea even where to begin with that one.

Exchanged comments with Cloudflare's CEO on the topic and in my opinion it appears that they simply don't understand that their view of the situation is skewed.

Here's hoping that given they truly do appear to care about TOR users that they'll revisit the situation and find a better solution.

Here's a link to Cloudflare's blog post an the related comments on HN:

Tor can't possibly be the only signal of fraudulent activity though? It may be one that has an easy "solution" however, but one that's easily circumvented (one of the many free VPN services out there).

Prepaid credit cards are essentially anonymous, as far as I know.

This is a tough situation. I don't know about 94% of TOR traffic being fraudulent but I'm sure it's high. But I'm one of the legit users that gets taken out by blacklisting. I use a VPN service pretty regularly and it makes accessing my Cloudflare account and sites using it incredibly annoying.

Yes and no.

Yes: many fraudsters are ridiculously lazy, and fraud rates go down when the tor block is in place.

No: plenty of fraudsters access from elsewhere (and I put them through a separate fraud-detection-SaaS)

My understanding is that you can only buy prepaid cards after showing ID in many jurisdictions, and many other places require you to register them with ID in order to use the cards.

Signal according to Cloudflare isn't "TOR" but the IP's the are used by TOR exit nodes get banned due to them being shared and abused enough to trigger that IP being tagged as a source of trouble. I personally don't buy this, since I know of IPs they don't block again would get enough abussive traffic to merit the same treatment, but don't get the treatment TOR's IPs get.
