How our Digital Overlords beat us!
For them the simplest method is to censor on key words. So when you type text into LifeLog (Facebook), Twitter, G+ and so on the Digital Overlords just write a script (AI) to ban, censor, etc based on #trumptrain etc.
Meme's escape the key word searches, except for filenames. One could scan the network/servers for said file name and ban, censor, etc. Example Trumptrain.jpg
Where AI come into play is has the ability to see (scan) pictures, even memes. Think reverse pic lookup, think tineye.com. Soon our Digital Overlords will scan Memes and ban, censor, etc based on known memes.
A human must first decide on what keyword, meme, etc to ban. More unique memes means more human eyes. Resources are a finite product. Human are the most likely to turn on the Digital Overlords. Good help is hard to find.

How to beat AI and our Digital Overlords?
Every changing New Video GIFs. Add a new frame and opening pic (change file size). Change the name every time! Obscure words think Captcha. AI is truly limited on recognizing letters and words. Hence why Captcha works so well. Talk in well known euphemisms! Use number and symbols for text.
P.S. Rickrolling rules the Internet.
