Any risks with a Nulled version?

Does anyone have any experience with nulled XenForo forums being brought down these days?

I created a forum 3 years ago, went for a nulled version of XF and within 2 weeks my provider got a complaint, and decided to suspend my site. I decided to go for phpBB at the time, and migrate the backup of my old site, but XenForo is looking much more developed, and I'm thinking of going XF again.
