The other day I was checking on my two ethereum accounts (they are 4+ years old).
There was a small "!" in etherscan.io that caught my eye: it alerted me that my first mainnet account hash is found also in ropsten and kovan testnets. My second mainnet account was replicated only in ropsten.
I got ...t scared!
Same account hash means that it has been generated from the same public key as mine, while that in turn has been generated from the same private key that is mine (see here)
Investigating more on the replicated account in ropsten, I saw that it had some "airdrop" tokens in there.
So has someone copied parts of mainnet into ropsten and then that same pumpkin fairy has airdropped me some tokens? I would have appreciated him/her not doing so & not giving me this halloween scare-time.
An explanation of what is going on would be highly appreciated.
