among
Factoid there are two of them that mention Multibit specifically the following:
•Creating a Bitcoin client that fully implements the network protocol is extremely difficult. Bitcoin Core and some of its derivatives are the only known safe implementations of full nodes. Some other projects attempt to compete, but it is not recommended to use such software for anything serious. (Lightweight clients like Electrum and MultiBit are OK.)
this wallet is now deprecated since it is no longer being developed and it contains bugs that were never solved. and it has been a year. so it is "not OK" to use it anymore!
