I think this one used to give away up to 0.5 BTC

The only problem: He hasn't been online here since January. But you can check his profile and contact him through his site that is listed there >
https://anycoindirect.eu/en Hello timmy333,
We can see that you are in need for some coins on the BTC Testnet to facilitate some testing. As you stated, most of the popular faucets for TestNet are temporarily disabled because of the flooded network.
To enable you to make the necessary transactions we have just sent you 0.5 from one of our Testnet wallets. Unfortunately we cannot send you more than this since because our supply of Testnet coins is rather limited.
Good luck with your test transactions and let us know if everything worked out!
With kind regards,
The Anycoin Direct team
