I've noticed a few members who put their account on hiatus daily...

Because they’re special. And need everyone to know how special they are. Either that or they don’t know how to just log off properly

The glamour of the place fades. I don't think it will be long before I 'vanish' too...

Probably dangling between leaving forever or staying.

I deactivate frequently for privacy. Don't want anyone to know I am on Sw

No messages or notifications when you "leave". Thats my guess

That’s a strange habit. I don’t understand it.

Maybe all the cool kids are doing it

Daily!? That's strange.

A break. Something I need

Hello Friend

It's an attempt to stay off of SW so you can stay focused on something.
If you compulsively check SW like I do, it is like an extra step prior to logging in to allow yourself to rethink your compulsion.
