Physing as regards to cryptocurrency is basically a type of cybercrime in which people are duped into giving out personal details of their various crypto assets e.g a private key or a master key or recovery file etc. This is done by the use of emails, texts and so many others. The fraudsters tend to pretend to be administrators of certain crypto sites so as to make people feel they're legitimate after which they steal your crypto assets and you most probably never hear from them again. People have actually gotten phised on steemit alot. I have a friend who was tricked into giving up her steemit password which led to her losing her account.
The most frequent type of phising I see on steemit is what I call the 'crypto-exchange scam'. People tend to make mistakes when typing the names of the accounts that they're sending their funds to and accounts like bittrex, poloinex and deepcrypto8 which serve as gateways for people to send their steem or and to and from their bittrex, binancr and poloinex accounts respectively are the major targets. Fraudsters open accounts with similar names to the above stated accounts and wait for people to make the mistake and transfer funds to them. Such accounts include bittrexx, polionex, deepcrypto88 and so on.
Upvote and steem delegation services like minnow booster aren't excluded, as they are also targeted by fraudsters.
