Are device unbans normal?

So, I was device banned and account banned last year in January but then my device got unbanned 6 months later in July and I was able to create a new account. I’ve been wondering this for a while but is it normal for me to get unbanned from my device? I was able to even get a new phone and transfer my data and I haven’t gotten banned. I’ve had my current account ever since and I haven’t gotten banned. Am I in the clear?
