Invest in a trebuchet

How lol??

Repel evil with what is better. :) from the quran

Getting rid of them should always be an option.

Ignore them... They only ever have the power you give them...

Be boring

If you don't provide anything they find of use, they will move on anyway. They need an audience or a resource.

Refrain from being either.

If you don't wanna cut contact, cut access to the things that you don't need third party opinion on. It's less noise for you.

Walk away and never engage them
