I've contacted GitHub. They suspect that it's due to misbehaving spam-detecting robots, so they just unflagged my account "twice" but still doesn't work. What should I do?
Reddit is the best way that works consistently https://www.reddit.com/r/ethdev/comments/61zdn8/if_you_need_some_ropsten_testnet_ethers/
To get ether from the Rinkeby testnet, you have to post your ethereum address to one of the following social networks:
- Twitter (public)
- Google+ (public)
- Facebook (public)
Once you've made the post, copy the public post URL and paste it into the Rinkeby testnet faucet. You'll get your test ether quickly after that.
We have created a universal faucet here It is just a captcha for validation so it should be easier to use.
SOLVED: Make your tweet public, in this way Rinkeby can validate. https://www.techwalla.com/articles/how-to-make-twitter-public#targetText=When%20your%20Twitter%20account%20is,to%20make%20your%20account%20public.
