In case anyone isn't aware, connections like that are literally called 'illegal' techniques in LEGO parlance.
Illegal building techniques are ones that aren't allowed in official LEGO sets, which always use building techniques designed for and intended by LEGO. The reason they're called illegal is because they stress the blocks in a way they weren't intended for, causing various kinds of material failure overtime.
As an example, the blocks in the example above slowly deform over time because, slowly warping until they don't connect very well to other blocks or each other.
