Do any of you pay for carbon offsets?

Of course, it's better to emit less carbon, and support systems and policies that emit less carbon. That said, carbon emission is unavoidable, and I'd like to minimize that portion of my impact as much as possible.

I am definitely willing to pay to offset my carbon usage, but I'm under the impression that this is mostly a scam. Does anyone use these services? If so, can you tell me what reasoning or sources you used that satisfied you that the service your chose isn't a scam?
