If my answer seem short and to the point, there's a reason for it.
Some years ago when Ohio Rolling Cash5 jackpot was nearing $500K, a thread about it was very active and one post from a LP member (who's no longer active) in California who said he usually played RC5 when its jackpot was high through his sister by wiring her money to buy tickets until she recently moved from Ohio caught my attention.
I thought since I was planning to spend $20 on tickets, I could afford to spend half of it helping a fellow LP member and maybe myself too and posted if he would PM me up to 10 lines before the drawing, I would buy them at no cost to him and split any winnings minus the cost of the tickets with him.
He PM me that he usually sent 80-100 lines to play for different games and he usually got a gratuity of $50-$100 before sending those numbers depending on the game. That's when I learned LP members who want to PM numbers to other members aren't their friends but scam artists. If they want to share their numbers they will post them on the predictions board or a thread for everyone to see.
