This section on rules entailing Expiation with Forfeiture explains what should be done with money if it is accepted by a monk.
It is a major issue in my opinion. There are other more serious offences, such as sexual misconduct of various kinds, but if lay people didn't offer money to monks, most corrupt individuals would soon leave the Saṅgha, as there would be no advantage in remaining. We get free meals, and free accommodation so that we can meditate, study, and teach the Dhamma. We do not need to be paid for the work that we do as our basic needs are provided by lay supporters.
