Reporting it will be a harsh move, why would I do that to get someone punished for a very little unsensual activity
Because, if we let users get away with this, there will be no limit to the amount of begging PMs we'll receive. You call it harsh, I call it necessary.
If it become an outbreak of disease then we may call it necessary but it looks like only one or two unusual activity. If a random user PM me for money or even for anything else that does not interest me, I will first ignore the PM until he starts annoying me with more PMs after waring him once or twice. Members need space to interact with each others, it's okay for me if they want the interaction in PM as long as I have the same interest.
