Moderators (requests and notices)

Well, what one can do vs what I do are different questions.

Most will look for non-IP ways of identifying a user, such as storing tracking information in the client (local storage, cookies, timing information via CSS leaks), or by fingerprinting clients and using that to de-anonymise visitors regardless of IP.

These are effective, and easy to do.

I philosophically am against intrusive tracking... so what I do... is just ban people and consider it a cost exercise. Their effort to register email addresses and post spam exceeds mine to ban them.
