I made a new SCP that I came up with some time ago.
It's roight here at Tab 3: yay
The idea of anomalous, virulent advertising is pretty decent, although I feel like I've seen it before. Unfortunately, the way that you've presented it here isn't that interesting and mostly serves to confuse. You never explain anything about transmission or what products or give any real information other than the absolute bare bones. Plus, the use of the Factory and Wondertainment feels very weird, as they add nothing to the article other than "WOOP WOOP! GOI! GOI!" The stuff about banners and t-shirts and such seemed similarly odd.
However, I think that there is still some possibility with this. My suggestion would be to zero in on a specific form of advertisement that you notice fairly regularly. Could be social media accounts for Hardees, or those godawful "hip" Tumblr ads, or maybe those comments that always pop up in Disqus about "MY SISTER MADE $800 A SECOND BY GOOGLE WORKIGN!" Something. Then, try to work backwards. If you were a… let's say anomalous entity, and you maybe had difficulties interacting with the physical world, what would you do? How would you try to get followers? Maybe characterize it a bit. Then work forward, trying to figure out what sort of advertisements they would create. Then write that up.
