again few strange wallets

wallets protocol 2.0.1   - now single IP ( also a node for Hyperstake and some other coins )
wallets protocol ,,zero'' - this is single IP in China 221.232.159.150 and for sure it is not a exchange

my question :
1. if someone modifies 2.0.0 wallet to such extent it shows 2.0.1 protocol or ''zero'' protocol would it be considered legit ?
2. for what reason he does such - possibly - hard work ? where is a profit ? could such a wallet stake much faster ?
