I originally came to this site for Spider-Man movie news. Should I complain that it reports on other Marvel or DC characters now? If they weren't reporting on non-comic book movie news, people would be complaining about a lack of news/posts in general. SHH is hardly the only site to report on things that don't relate to their main focus. It may have started out as a comic book movie news site, but it's now a more Geek-focused Movie, TV, and Comic news site.
It's not like you're paying to come here, so maybe you should just enjoy the info you want and stay away from the rest. It's not hard. You can just click on the Heroes tab on the main page and only read info on the subject of your choice.
Also, using a vague quote from a trailer in the headline to a story isn't really a spoiler. And if you're trying to avoid all that stuff, you probably should just avoid this site (and the internet altogether). I've never had anything spoiled for me on the main page that wasn't my own fault by clicking on something I knew contained spoilers.
