Why yes I do Miner, especially for so minor of an infraction especially if she confessed her transgression, especially if they are only online etc etc.
Of course this all depends on a number of as yet unknown factors as to what is appropriate in my opinion.
Perhaps one or both of them will elaborate.
If its a continuing offence, or not really an offence becuase no one told anyone not to do it hasnt been made clear yet.
If its only a first time offence, mabey a few spanks or just a stern talking too are more than plenty. Mabey wearing a clothspin on the toungue for an hour for the lie she confessed too of her own voilition.
If its an on-going, happens all the time thing, then they should be sitting down for a talk, becuase no amount of "sugested punnishments" are going to change whatever is cuasing the situation.
