Prepare more than an hashtag. When Twitter kills one, be ready with another. Use only that, everybody only that, then another when it's time and so on.
Be ready on Facebook too. Many elders and housewives are there. Facebook users need a softer approach, don't scare/scandalize them.
Use short videos on Facebook, Fb shows videos far more than images (it's the algorhythm). Post videos in groups, ANY group, but don't flood or they'll ban you.
