Thanks for this post. The article discloses that yes, TC had a Twitter account. Most likely ET had one (or more) as well. Someone up there wondered if we had Twitter accounts for them. I'm also wondering about Snapchat.
Editing: Forgot link to TC's twitter account, if some had missed it earlier.

I know ET had a snapchat. On her IG, somewhere further down she posted the screen name telling people to add her.
