why do people gift?

literally as the question states. WHY? even "hater" pages be gifting her roses ONLY so she can see their name/pfp but its STILL money being spent to her. it often seems people be just sending her shit just to get a reaction out of her but (IN THE WORDS OF ASH) "at the end of the day", she gets MONEY.

if you have sent her money in the past, can you please explain why? im just having a really hard time understanding
