Yeah the - 1 + 1 was weird to me too, serves no purpose.

I can see how choosing a new random number for each fetch would prevent the server from caching the response, I suppose.

I can't imagine this code was written in any other fashion than completely rage-induced, with shaking fingers and high blood pressure. 😂 What a putz.

I guess it's just a pattern to easily get a number between a and b, going (b - a + 1). Or maybe this is just vibecoded lol

Seeing (100 - 1 + 1) definitely bothers my brain lmao

Looking closer, the whole calculation bothers me now. Why do floor() + 1 instead of just using ceil ... arghhhh

There are a lot of these sorts of things. Look at the RegEx used in the block list. The author will likely be surprised that RegEx supports * and +.
