With Lyft, I actually received $150 in credit total. I picked a coupon for $50 at SoMa food park. Then I received $50 credit for my 5 star rating, and then suddenly my dev phone also received the same $50 credit since it had a dormant Lyft account that I only used in 2014: apparently it had a perfect 5 star rating too.
EDIT: I wasn't going to engage but with this many downvotes I feel obligated to explain myself. Like I commented below, I'm not trying to tell you how to act. I merely wanted to point out that just because it's easy doesn't make it not wrong. As a group of people who actually run their own companies I would expect us to know better.
With Sprig, I invited my second dev phone as an experiment, but I have never used the remaining credit- I simply have very little use for their service. And I can prove that. How is that stealing? I think you should be careful laying anonymous accusations.
Some of you guys have a promising career waiting for you at the RIAA.
IMHO it'd be more of a Tragedy of the Commons type of scenario, where a few users taking advantage of loopholes in the rules might hose the deal for everybody.
I think you are getting down voted because he explained the entire situation, and you generalized it in a way that strips his actions of context.
For instance if someone told me your were a thief, I would instantly form a poor opinion of you. However I would form a very different opinion if I knew the reason you were a thief was because you posted your bike on craigslist, and then broke the terms of service by re-posting those pictures elsewhere. Thus anyone who introduces you as a thief is doing you and communication a disservice.
