Someone visits my website

>someone visits my website

>autobanned from my site depending on what other sites they might frequent

Is this possible? How can one do it?

You could check for cookies

WebAssembly
+1 overflow
C++

No you couldn't.

And no it isn't possible.

I guess your could simply just put a pop-up asking them what sites they visit
If they're retarded enough they answer and get banned

You could probably look at the HTTP referrer, but that's about it

You can't force a client to do anything if you don't operate it. Are you fucking retarded?

Possible via CSS abusing. Link a list of websites, invisible ofc - if the browser marks the links as visited, filter.

Thats been fixed for the most part iirc
Testing load times for things to see if theyre cached might work but might not have perfect accuracy idk

Can you ban mobile posters by blacklisting mobile useragents?

ZUCKERBERG IN TRAINING

>what is same-origin policy
Retard.

So what does the browser do when you access the status of that link? Treat it as never visited?

Not without a compromised browser you can't

I see you’re new here, summer friend :) come on, let me show you around!

Idk im not a faggy underpaid underskilled webdev soi

>mobile useragents
not tcp/ip fingerprinting to blacklist windows and Mac users and clear up /v/irgins and consumerism generals

Twitter does this to autoban people who go to websites they don't like.

either that or not give you any information if you check

>>someone visits my website
