I have switched to faucetbox.com, which I should have done a long time ago. Their migration is easy, all you have to do is upload a script to your root directory and input your faucetbox API key, and that's it. The 3% fee on deposits that faucetbox charges is somewhat annoying, but I guess it's worth it, they need sone money for their efforts.
it is very clear, and thank you also MakingMoneyHoney for your precisations.
I've tested faucetbox following your instructions, i've just to add the modification i did in the microwallet script also for the new one
