It seems we have uncovered a true enemy of our Equality here.  
Don’t worry. You will only be gone for a little while. You will feel better in the end. Trust me.

Hah, what a silly image, it will be a permanent revolution. Equality will rule for a thousand years and more!

Sounds like you need more tact.

More than likely, it’ll be something in reference to pop culture or recent events. With the rise of Marxist groups across the globe, I was a fool to not guess this.
 
Next year? Loot Boxes and paid bug fixes. All fake currency (Unless we want to also turn it into a fun raiser. I would back this.), but you unbox badge fragments, site layouts, and color schemes. These are later used after the joke is over, as mementos of sorts.

You forgot the best one!

2015 was when all the ponies were running around the screen. 2016 was the joke about a pay version of the site (Derpibooru Premium).

I miss the 2017 look. I wish they had left it as a theme that you can select.
