Not sure if this is just happening to me (although I've tested both phone and computer) but pizzagate is not an auto-complete option for a hashtag, does this add more speculation to twitter trying to suppress/discourage tweeting using the hashtag #pizzagate?

e.g. if you were tweeting #throwbackthursday by the time you have #throw it would suggest the complete hashtag. If you type in as much as #pizzaga it will not offer you the complete hashtag.
