I use tor for exploring topics that I don't want to tie to my regular profile (ranging from professional software development, through health care issues, but also hobbies, fiction and nsfw content). Having these browsing in a separate profile and also IP address makes it much more relaxed to look for interesting stuff on the internet. (I am not really fond of advertisement that tries to sell me whatever I've visited in the past month, on unrelated pages.)

It saddens me that the default response is ban, increasingly so for services that need account, but even just reading a webpage can become tedious or impossible :(

Please, do not ruin this option, because even though you may not use it today, you may need it in the future.

Note: I also use tor for low volume crawling. When high volume is needed, it is more favorable to subscribe for domestic VPN proxies, so you may be blocking tor, but you won't block those ranges, and the robots will get their content anyway.

I constantly use tor as a way to get a third view when debugging connection issues for customers and malware infected websites. If you ever experience the issue of a customer saying they can't connect, but when you test it it works perfectly fine, tor is great to verify if the issue might effect more customers. As a side effect of it being ipv4 only, you can also test issues when one protocol work but not the other (there are alternative tools but tor is by far easiest at hand).

The traffic my servers receive from China, India, South America, Africa, and Eastern Europe, and the UK is also almost exclusively boys and exploit scanners.

You can block whatever IP addresses you like but the bot to user ratio of any given IP address is absolutely terrible. Tor concentrates a lot of traffic into a few exit nodes but by this logic most small countries should be blocked from most websites.

Have used Tor for accessing the Z-library and several other cases where sites where blocked or taken down. Not all of Tor is dark web shadiness or bots.

Probably depends on what kind of service you're providing.

I (a legitimate user) get blocked on websites when using Tor quite a lot. It's a pita. :(

That being said, there's no chance in hell I'd ever put a CC or similar private info though a Tor based network connection. Just in case... ;)

Wow, that's terrible, for reasons already explained to you below. Please reconsider.

How would you know if they are legitimate if you block them.

It's amusing to me that you're getting crushed on here for blocking/ "defederating" known IPs that you don't want traffic from, but I would bet that these same people would champion your right to do the same if you were blocking a spammy mastadon or lemmy instance that you didn't like!
