Syndicated copies to silos include "Syndicated to:" text · Issue #32 · dshanske/syndication-links https:/

The text output from Syndication Links (the default text "Syndicated to:" ) shows up in the syndicated copies (and I'd generally think that most wouldn't want it from a UI/UX perspective). I've tried syndicating to most of the major platforms and Facebook and Tumblr appear to be the primary offenders.
