Unless the other person deposits cash into your account then it is possible to reverse the transaction. This is true for all banking transactions. Period.
If you spend some time reading comments above, you should know CASH deposit is reversible for BoA.
No they are not. The person who posted that is likely spreading FUD. The only real possibility to do this is to convince the teller to give the account "intimidate" availability for a check deposit so it would look like a cash deposit on online banking, but it would really not be a cash deposit.
