I'm putting this in fanfiction because… I dunno, you can't get much further from "actually related to Sentinels content" than this.
The SCP Foundation is a collaborative speculative fiction writing site based around a shady inter-governmental organization dedicated to capturing, containing and studying the various anomalous objects found throughout the world. I've been writing for it for six years now. My latest addition, SCP-3231 is an oblique takeoff of the "#BringDebbieBack" meme, because apparently legitimizing memes that no one on the wiki has heard of is what I do now. Like I said, it has literally nothing to do with anything actually Sentinels-related, but I figured some people here might be interested. And if not, that's okay too. 
Okay, but I'm working on some SCP-themed Sentinels decks too, shh, don't tell nobody <.<
