That sounds really lovely, but it’s also really vague. Especially if you’re not even sure it was a Steve/Tony fic. I haven’t the foggiest clue what it might be.

magneto joins x-men? when and does it last? How long?

Oh, the saga of Magneto.

It's in flux, a lot of the time, and I'm not sure if he ever officially joined. You also have to bear in mind that "The X-Men" is kind of in flux as well. Like, at the moment, Magneto is technically some kind of trustee of the Xavier School, which is currently being run by Cyclops out of an abandoned bunker. But the Cyclops-oriented X-Men aren't necessarily the good guys.

I… is comicsverse a totalitarian cap led verse now? Because that is absolutely how it seems. Be good and you won’t get into trouble? What? And they need to plaster this places? I don’t even know. What is this madness? Is it just out of context?

It's a little out of context, but mostly it's just a joke :) It's in Deadpool, a satire comic that often involves unlikely background imagery (this is the same comic that had Coulson drinking from a flask as Deadpool blows up Helicarriers, and SHIELD agent Adsit entering HQ through a lingerie shop). 

For historical context: The Comics Code Authority for many years dictated what could and could not go into comic books before it would stamp them, and it was hard to get your book sold without a CCA stamp. The CCA banned things like "terror" or "horror" in the title of comics, portrayal of "illicit" sexual relations (mostly, I think, referring to homosexuality, possibly also interracial romances), and other things that would destroy the youth of America. :P
