There's anything nothing wrong with people adding lists of people on social media regardless of gender as long as they don't have haraam intentions and they recommend each other to the obedience of Allah
What exactly don't you like?
You have to be careful about intentions because your initial intention may be good but because many people including myself forget about renewing intentions something good may turn into something bad very quickly.
I would personally avoid at all costs. Peace of mind that way Alhamdulillah.
Reminds me of this story.
