Follow collection with no handles #28
Description
If a Twitter collector is made using follow, STACK and Twitter expect all the collection terms to be account handles. If collection terms aren't account handles, they are given a "null" value for the "id" field in the terms list in the config doc.
If ALL collection terms aren't account handles, the collector will continuously through an error, saying it's getting a 406 error from Twitter.
We should add something in documentation reminding people not to include any spaces in collection terms using follow. If possible, it'd be great to even have a dynamic warning if someone tries to do that.
