It's a respect thing on both sides.
Don't get why "fans" take it to the level of tracking down celebs. From phone numbers and addresses to other shyt. That's unhealthy and unstable fam. Won't catch me at 5am waiting for an autograph and a picture. I'll just catch a autograph signing or say something real quick while keeping it moving if I see someone in public and eye contact is made. I also believe these "fans" messed it up for us normall fans in how celebs are on high alert 24/7. Not saying they weren't on alert in who they met in the past but it wasn't that high. Now they gotta watch out for muthafukkers like this
Or the dude that had that Paige cutout doing human in a flesh shyt around the house

Or comments under their social media pages
Females you too
Fans gotta know when to separate the character onscreen vs an everyday person you'll see on the street or somewhere. Sasha wasn't "Sasha" at the time,she was Mercedes/someone's wife/out enjoying herself. Sure she could've did a quick wave but like most have stated,those "fans" would've wanted more and more.
