Who called from 2101000001

Received cell phone text.    Wanted me to text back to "see their bra, LOL".     Added to spam and blocked this number 12101000001 and 12105382072.

Got a weird text (looked like an email) saying they were [***] and to text back. Did not reply.

Texted my daughter saying they saw her pic in FB, newly single to text them.
