Got one of those "we want you to buy reddit stock because you reddited really hard!" emails... on an account I haven't used for six years. When I did use it, I used it almost exclusively on a niche subreddit, too.
They're scraping the bottom of the barrel already 
This is in the dunk tank to dunk on me for once using reddit
The IPO email reads like a fucking phishing scam: “we would like extend you an offer to get on the ground floor of an exciting investment opportunity! Please provide social security number in order to get in on this amazing stock!”
Can't wait for the inevitable leak, doxxing the handful of redditors that aren't bots.
I think it's because that's exactly what it is. A scam. You have an userbase that averages around having a disposable income. So you pretend to be giving them an early bird privilege when in reality there's seventeen thousand asterisks attached. No redditor is part of the inner circle of people getting the lion's share of this investment call. Banks pull this all the time, especially in e-finance.
