Can users get away with using engines by first making silly opening moves?

So, I have seen some people play crazy opening moves like 1. Nh3 2. Na3 3. g4 and then seemingly play near perfection from then on. Now I don't have any examples and I am not reporting anyone just curious if planning to play really "bad" opening moves by making mistakes or inaccuracies then playing onward with the engine can trick lichess's anti-cheater protections? I assume this is a thought or question that is not new and I am sorry if I am repeating anyone's discussions just after having seen some people seem to do this I was curious what keeps them from getting away with it?

Could you link to one of your example games? I think that lichess would likely catch this.

1 Nh3, 1 Na3 and 1 g4 are neither crazy nor bad. These are very playable and good to get the opponent out of prepared lines. I can imagine that strong players play these to have more fun and to avoid long theoretical lines.

No this will not fool the anti cheat measures.
These ugly opening moves are usualy played when a player is very tired/bored.

While possible I doubt it would be ideal, since getting yourself in trouble from the beginning would put a strain on even an engine to either equalize or regain an advantage. Most likely a player will use an engine in the beginning to avoid mistakes and once having gotten a superior position play as a human when inaccuracies, mistakes, and even blunders are no real threat to ones winning chances.

@tpr Of course these are bad. They don't control the center and develop poorly. They're just not bad enough to not be playable against amateur opposition.

@BigGreenShrek I have seen these moves played at master level over the board so these are neither bad, crazy or silly.
They do develop and control the centre.
1 Na3 is followed be c3 and Nc2 developing Nb1 and controlling d4.
1 Nh3 is followed by g3, Bg2, o-o, f3 or f4, Nf2 developing Ng1 and controlling e4. The advantage of Nh3 as opposed to Nf3 is that it does not block the f pawn.
1 g4 is followed by h3, Bg2 developing Bf1 and controlling e4 and d5. International Master Michael Basman played this way regularly even against grandmasters and despite they knew he played that way.
The big advantage of these moves is that these force the opponent to play real chess right away instead of reeling off memorized theoretical lines.

@tpr Indeed, they do have the benefit of getting the opponent out of their book. However, if you're claiming such moves are objectively good, or control the center, or in the case of the knight moves develop in a sensible fashion, we're going to have to agree to disagree. I don't think your reasoning that e.g. Na3 controls the center is at all persuasive. In fact, it seems manifestly bad to me, but others can judge for themselves.

Andersen played 1. a3. I doubt that he was a cheater :)

It will not fool detection. It was a pretty common way to cheat back in the day, the cheater got kicks from winning from bad positions, it allowed him to showcase his "superiority". It's part of the cheater fantasy.
