Agreed, Prof. I think it's even worse when a user exploits a black hole glitch - basically, a cheat which makes the goal piece free of any restrictions - then drags it to the goal, and then posts it with a snarky comment. To me, the comment suggests I test for cheats. Uhh. What? It's a flaw in the physics engine, not in the level.
For 'Shunts', it's true the goal piece can be directly grabbed with the mouse, without any trickery (and I've made a few levels where I didn't notice that, and endured remarks on my IQ), so I think that may put the burden on the level - but I think it's still unchill to post a 1-tick 0-piece solve with a snarky comment. Those usually come from noobs or users who've created no meaningful levels of their own, and they are just projecting their own insecurities.
Over the years, Prof, your levels and solves have been top drawer - well-thought combinations of efficiency and artistic design. Ignore the comments - some of these kids are ill-mannered. And we've seen a rash of new ones posting useless levels lately - it's even been too much for Skeezix.
