The reason you got so much backlash for your OP is you said or implied that Taxi was a scam. Since many of us know it's not, it gets our backs up. If you had just expressed frustration that you got a lot of forwards but no contacts, that would have been different- at least to me.
Taxi is a totally honest and transparent company. I've known Michael personally for at least 12-13 years. However, a company can be legit and still not be the vehicle that achieves success for any one particular person.
Since it hasn't worked out for you, it could be time you stop renewing and try other methods. But I do hope you won't throw around that "S" word. It's just not so. I had at least 5 placements on "The Young & The Restless" the past month or so, all because of a forward to a Taxi client library. So I know it does work. That doesn't mean I haven't had tons of forwards with no callbacks just like everyone else.
