Need a quick break or want to discourage that bounty hunter that is chasing you. Here is what you do:
Stand close/next to a non player building that you can’t enter. Call out a mountable pet (now the pet should have some part of it’s body in the structure). Mount the pet and you can ride inside the building. Dismount from pet and store it. Now feel free to LD or AFK and be protected. Yes they can track you but they can't attacked you at all. this works in PVP as well.

Ive seen lots of people doing this. Though I have never tried attacking someone inside a building or under a house.

I guess you get the "Cant see target" message even while you standing close?

yes even if you follow them in the wall it wont let you hit them for some reason, this is a well known exploit

There is a danger that they will know this exploit as well and use it to get in. I do believe they can attack you while they are in there to
