I do not really understand the fraud system...
Many addresses on faucetHub are public or in referral links,so every one can use them...
About autofaucets:
I have used once because I have not realy knowed about...it's HORRIBLE
Here as well...every one can use addresses from other people.
About multi addresses:
Often an address is asked...and then once logged in you see that payout is only possible or realistic by FaucetHub...and so you have an address more deposed on FaucetHub.
On the net are so many faucets,that it can happen the same faucet is used with different addresses.
For me something is not clear about this kind of fraude if it is FT who manages it...i'm afraid for my few satoshi I have on FH (lol)
I dont understand about which possible fraud mexicantarget and you are talking about. If its to much to be explained then forget about it, im not interested and not wanting to waste your time explaining to me.
Could be a fraud to claim on someone's else address but i dont see the logic behind it : why someone would waste his time to see bugged/infected shortlinks for somebody else ? Maybe a relative ?
My relatives are women and they dont know what is a bitcoin ,lol , they dont know even how to surf on internet , nether how to use a computer

Few days ago i met an old friend and when i told him that i see ads to collect small amounts of satoshi (bitcoin) ,he told me that he don't trust bitcoin because he heard that the bitcoin is a fraud scheme on internet.

On autofaucets the claims are way to low,
much lower , than a normal (manual) faucet and even if the EXP selling system will be added , i bet people wont invade autofaucets because are not paying enough so they won't overload the Faucethub with payments calls if someone believes that.
Thank you mexicantarget for reply.
