Its way to easy, create a page with a profile and cover picture of a beautiful sexy young girl (don't put a celebrity), then get add some three more pictures,
Edit the button to be send message, create a post with the "get message" option, put a nice pic and write something like Hi, I am single and bla bla bla.
Now you need to set auto reply messages, you can do this by Facebook inbuilt auto reply or other bots like many chat which is more better, the auto reply should be like " Hi
@username , if you want to chat with me share my profile or posts to 5 groups, if you lie I won't chat with you"
So whenever someone shares to groups others will see a pic of a cute girl with the "send message" button, when they send message they will be requested to share the post to other groups,
I did this and got 1.2 M engagements for 3 days, the shares were so many, the inbox was flooded, I used this as a traffic source to my site, the auto reply messages tricked people to click the blog link and Facebook banned the page for this reason. I had 13k likes but they weren't useful for me at that time .
If you play it safe without attaching your blog link in the auto reply message you will just be alright,
