This kinda thing is too casual. If they don't collect it, its a few words to remove. Just fucking remove them.
Many states have statutory requirements to provide disclosures in regards to whatever laws they have which may potentially have some manner of impact to the consumer and in most cases, said statutory notifications need to touch on all points of the statute in question. If you don't fully comply and do business in the state, then you open yourself up to fines, so usually you'll just dump literally every point into your disclosure so some CA auditor doesn't find you in non-compliance. This goes for other states as well which have statutory disclosure requirements.
He's talking about two different things
When you use a radioactive weapon like a fatman or nuka grenade, if you have PVP turned off, the explosion doesn't hurt your target. However, fatmans and nuka grenades create a field of radioactivity which ignores PVP flags because it is considered an environmental effect, so your character still takes the environmental residual rads (which last for a bit). Some trolls will abuse that, but trolls are fairly rare from what I've seen outside of free weekends. It's a known issue that has existed for a while now.
The actual nuke, to which you responded, is actually a good thing. The zone becomes ultra irradiated (no surprise) and spawns bosses, special plants to harvest used in high end crafting, and high level monsters which drop crafting items needed to make stable flux, which is a crafting component in end game items/desirable mods. For instance, a lot of the X-01 PA mods require stable flux, as well as the ultracite ammo mods, etc. You have lots of time to get out of the blast radius (everyone on the server literally gets a quest called Death from Above started, a giant red circle appears on the map to show where the nuke will land, and a count down appears), so you can't kill someone with a nuke unless a) they are asleep/AFK/not paying attention at all b) so horribly overweight with shit that they cant fast travel and they refuse to dump anything in order to escape.
Unless it's the battle royale mode, in which case you have 15 seconds to GTFO or die lol
