Woman refuses to help sister financially after she promotes MLM at her wedding; AITA?

Hustling your scam 'business' to guests at a wedding usually isn't on the Bingo card for 'things that could go wrong'...

We've heard of Bridezilla, relatives wearing white, exes showing up uninvited, and runaway grooms, but what about a 'hey girlies I have an amazing and lucrative financial opportunity for you' presentation at the open bar? So, when a conflicted sister decided to consult the moral compass of the internet otherwise known as Reddit's 'Am I the As*hole' about her sibling's money problems, people were ready for the family wedding gossip.

AITA (Am I the As*hole) because I don't want to help my sister financially because she promoted her MLM at my wedding?

I (29f) married my wife in October last year. Best day of my life. My (32f) sister Bianca has been in MLM for almost 3 years. She has seriously become another person since she started her 'business.'

We share some group chats and there's not a day that goes by that she doesn't send out catalogs, promotions and walls of text about how lucrative the opportunity is.

About the topic. It was the beginning of the wedding reception. My wife and I are talking to some of our guests when our wedding planner frantically approaches us and tells us that there is a guest handing out MLM business cards to arriving guests. Turns out it was Bianca.

I asked her to stop and she did, except she spent the whole night trying to talk people into the business. In the grand scheme of things, what Bianca did was insignificant because my wife and I were very happy that day and there were no major problems, but I still get angry when I think about how uncomfortable it must have been for the guests who were subjected to her presentation.

Fortunately, they graciously accepted our apologies. Every time my wedding is mentioned, someone is sure to mention my crazy sister who was promoting her MLM. So incredibly embarrassing. Bianca and I haven't had a lot of contact since then.

Yesterday my mom called me and after a bit of catching up, she told me that my sister's business hasn't been doing very well and she's been struggling to meet her monthly quotas so now she's behind on rent and needs money.

Bianca asked my mom for money and she in turn asked me to help her. I said absolutely no. She embarrassed me at my wedding, she didn't even apologize and I was absolutely sure she was going to use the money I gave her to get into another MLM now that this one was no longer working for her.

My mom said that I'm cruel and rude. She said that she did not raise me to betray my family. I told her that she is just feeding my sister's fantasy world and making her believe that at some point she is going to be successful with her MLM. AITA? We're not in speaking terms right now.

Yikes...I guess none of the wedding guests purchased a starter pack? Luckily, the jury of internet stranger was eager to weigh in. Here's what people had to say:

Nta. Your sister's business isn't failing, she's just not able to afford to continue being a customer in the pyramid scheme. The sooner she hits rock bottom, the sooner she'll learn she was taken advantage of, and people helping her (slowing her fall with money) will only be brought down with her.

NTA. “My sister’s business hasn’t been doing very well.” She doesn’t have a business. She has a spot at the bottom of a pyramid. What she did or didn’t do at your wedding is actually irrelevant when it comes to whether or not you should give her money so she can sink it into this or another MLM so she can further fund the dreams of her uplines. If your mom wants to help her, she should help her get out.

NTA. Anyone who tries to sell me MLM crap is dead to me.

NTA - you really don’t need a justification to not lend/give someone money. It's your money.

NTA - enabling her is the opposite of helping her.

MLM’s are so like gambling. If you ever change your mind in the future I would offer to directly pay a bill rather than hand her cash.

So, there you have it...

Everyone agreed unanimously here that this bride isn't wrong to refuse to help her sister out, but this family should probably have a serious conversation with her about pyramid schemes. PowerPoint presentation on scams at the next wedding? Good luck, everyone...
