Intent isn’t the same as what will happen, the law does prescribe what he must do, and if that violates his intent, so be it.
But it does mean he’ll presumably be on the lenient side of what he’s allowed to do, which means it’s very unlikely Trump’s going to jail as a result of this conviction. Unless he ends up with a negative recommendation from the probation officer, which seems unlikely from what has been said publicly. But I wouldn’t say “absolutely not” yet.
I haven’t had this happen personally, but are you allowed to edit your hosts file? I’m assuming those IP addresses are coming from DNS resolution, and if you hardcode those DNS entries to resolve to 127.0.0.1, it’ll stop the ads.
nslookup <ip address>
should give you the domain names, if not there’s DNS logs in Event Viewer that should tell you.
