Yes, sometime in the last 2-3 days, Instagram banned the hashtag #porsche and all its derivatives (#porschegt3, #porsche918, #porschecarreragt, etc).

It seems to have something to do with Instagram’s latest wave of “shadow bans” that target hashtag spammers by making their posts not show up in the hashtag stream.

Not sure what Porsche did to get lumped into this, but hopefully IG sorts it out quickly enough.
