Custom Sim passed to me through Simport!

I think if you install your 3rd party CC through the launcher in Simpack form, that's the CC that's getting transferred. Not the 3rd party CC that's in your game in package form. Since I only use CC that's in package form, (I combine my CC together through s3pe) I don't think that's what's being transferred. That's why I don't download sims from the exchange because Simpacks are KNOWN for attaching itself to different files. Most modders and CC makers in the community shun the Simspack form altogether. So if I send a sim via Simport, the sim will transfer, but all you have to do is delete it from your launcher and your sim bin. If you know how to clean your cache folders and you're only using packaged file CC, then simporting should be safe. But no one has confirmed that a package file has gotten through on Simport. So I'm willing to test the theory out.
