There are quite a significant amount of "older accounts" that are doing the same thing. I suspect they were made this summer, with the time frame of the election in mind to become active. Do a check on the posting history of an older account to see what has been posted or IF they have posted. Don't simply take a non-handshake account at face value as being trustworthy.

For example: the Santa_Claus account is 56 days old, yet just starts posting last night.
