Alright, my two bits, here. Got a little bit of background on this due to some events on ye olde cesspit, TGC. Nukes of a certain size and capability can be considered superweapons. They are not, however, on the banned/superweapon list. On TGC, I got into motion the production of 100 megaton nukes for use against the enemies of the Mandalorians. For reference, 100 megatons is the largest the human race has ever looked at building while 50 megaton warheads are the largest ever tested. It was so devastating that some of the designers who had created it for the Russian government to test turned to pacifism and/or joined the anti-nuclear weapon movements available after the test bomb went off.
For something like a starfighter bomb or missile that can take apart a few city blocks or maybe a bomb designed to destroy a building or a city block, you can probably not worry about it. That said, anything bigger runs the risk of getting a report. Why? Because you don't dodge a nuclear blast. Weapons with a lethal Area of Effect and a high enough devastation factor can be seen as an instakill weapon. This means the recipient of the attack has three options: die, godmod, report.
Some folks are easy about their characters and such. If you spent post after post of setting up the bomb/launching the missile, plot device after plot device, and all sorts of openings for folks to stop the bomb or blast... they may just be okay with losing their character to the blast. For others, this forces them to somehow break a RP rule in one way or another. Either by godmodding and surviving the blast, metagaming into finding a lucky nuclear bomb shelter, powergaming a way to endure the attack, or some other form of rulebreaking. Personally, in the events I've used a weapon like that, I legitimately didn't care if they did or not, because I knew the power of the bomb or weapon itself and we all got along about it. I also did the first bit and took post after post and page after page to let them stop me, even going as far as to find each and every participant in the thread and tagging them to make damn sure EVERYONE knew what was going on.
The last option is the one that gets progressively more likely the bigger you go with the bomb. If you drop a 100 megaton bomb on a thread, even with all sorts of prep and not caring if people handwave out of the attack, you will probably get reported very quickly. If you're gonna wipe out a planet's population, make damn sure you have your i's dotted and your t's crossed beforehand. Otherwise, you're gonna get hit with the Tefhammer or the Admin Axe.
Ye be warned.
Here there be Tefkas.
