A very interesting topic has been raised.
What can you do with a user you don't know and who only has the Internet?
This is the biggest misconception. The Internet is one big LOCAL network.
It all depends on how much you need a user.
There are people here who have faced a permanent ban. All your local IP addresses. All the names of your network computers. All your software license numbers. All this is on the Internet. So, if a person has got you or you need to find him, the main desire is there, and there are tools and information.
And movies about how a hacker hacks something are very far from reality.
You may ask why this nonsense

The answer is that if LP intends to annoy you or block you, he has the opportunity to do so.
And here is another question - does he need it? How much will he be interested in this or that person on the network in order to make certain efforts and resources ?
This is purely information. No trolling and no hard feelings. Peace and no war
