I had a funny idea...
Suppose I am vegetarian. I create a website praising the vegetarian life. But there are those who like meat, from Serbia or Texas for example. And my website gets trolled by specific meat activists.
Now on my server I could ban such people, via their IP addresses or range of such addresses.
Or... if I'm savvy, I could create another version of the website that shows up, when those specific IP addresses / IP range shows up. It can be whatever I want, it could be a really lame version of the real website, enough to make them think they're getting through, but isolated from my main website and its content. Or it could be something else. It could even be a meat-eating website that praises the carnivore life but in such a way that it is subtly ridiculous. Or maybe even so boring that no one will bother looking anymore.
This would be temporary because if they start VPN hopping/DNS server changing etc. they may get through anyhow.
Wouldn't that be interesting? Might be a lot of work however. And it might be unproductive if people see through it. Or if I am a truthful guy I may want to proclaim who I am to all regardless. Or I might want to keep quiet. IDK.
Have fun.
