I think it mainly boils down to your ping to the server, i.e the amount of blocks you can place before the server realises and removes them.
If what you mean is that people can get annoying when they go on your res, then just take off their move flag.
Parkour. A secret build. An off access area. Redstone that can be messed with (pressure plates, levers with use on) Messing up minecarts. I can go on if you'd like.
I was having a problem with pistons somehow destroying a block on my sugar came farm, I rewired it and the problems seems to have gone away. But yes something when the pistons move it literally destroyed a block between then , no clue how but it did
If you cover your res in string then block glitchers can't bother you, may annoy you while building though.
I would need 3,600 string for each layer, I can't build anything, the string will be in my face,Il be easy to break I can go on and on lol
Sorry but as said in the past, we do not consider block glitching harmful enough to spend any development time on. Residences have adequate means to protect, and changing internals just to prevent people from being able to see stuff when we have a move flag that can accomplish the same thing just isn't worth time. Plus, some parkour courses even REQUIRE block glitching as part of the design, so it would end up breaking them if we did that..
