Probably only the FaucetBOX faucets created from "scratch" exhibit this behavoiur (how sad!

)
I think you'll be happy to hear, that we have a fix for that on our Roadmap

. Hovewer it'll be up to faucet owners to decide if they want that, because they'll have to update the script on their servers.
I have to request one more feature that could be useful (and will make FB better than the others).
Ability to send the payment + the ref payment in one request.This should decrease the FB load and speed-up the faucets that use it.
