This is what you do. Go on Facebook and find a dead account with pics or go on a social media platform no uses anymore like MySpace then get some pics someone person posted. Then Photoshop a filter onto them and edit the colors a bit then re-upload on to your new account. If done correctly it will be impossible to be searched for through Google.

This is some pretty solid advice honestly.
Another option, what I personally did, was I took my old Facebook account (I made a new one a couple years after) I took that dead account and deleted anything that mentioned my name in the posts on my wall. Changed all the info, and used a bot to mass add friends (in addition to my previous).
Using that method, it has posts from other people on the wall, and actual activity on the account. Just need to make sure there's nothing to "truly" identify you left on the account. Double check using www.stalkscan.com

Woah that's actually smart. Cause then the account won't seem dead anymore since the bot is adding friends. Brilliant
