I am so over MLMs (which includes Cambridge!).
I currently have FB friends doing NuSkin, Osborne, Forever Living & Scentsy. The Scentsy is the worst, as one FB friend has recruited another, and a third is thinking of joining.
The thing is, they are my FB friends as I'm interested in keeping in touch with them, their children, their hobbies, their lives - these are the reasons we became FB friends in the first place. Instead of which, almost every goddamn post is an attempt to sell something or recruit others to sell something, and I'm utterly fed up with it. I've ended up unfollowing a couple, hoping that give it a year or so, and they'll get past it. One of them has gone a bit quiet on the selling, so hopefully that is done. Another one, I really feel for - she is posting almost constantly with new items she has bought - which I think she is buying to keep her points up & stay live, or some such thing. But her original reason for getting involved was extra money, and it looks to me like she's spending more money than she's getting. I feel so bad for her. But I feel if I say anything, it won't help, it will just alienate her.
I miss their previous posts - watching their kids growing up (never see that unless it's a pic of their kids being used to promote a product), enjoying mutual interests.
I do try to have some sympathy - many years ago, when I was younger & more naive, I got mixed up in an MLM scheme, and when I look back on it now, I'm so embarrassed, and feel so bad for what I put people through (this was before hunbot days) - I wasn't a total dyed in the wool pain in the arse, and thankfully came to my senses. But you know what - these MLMs haven't changed a bit in that time - the script is just the bloody same. So I try to understand that they've been swept along in the dream of not having to work, being a millionaire, etc. I've been there. And admitting you got it wrong means giving up on those dreams, plus turning your back on (what seems to be) a supportive community. But hell it's hard sometimes - I just want to scream, or ask if they're keeping a spreadsheet of costs!
