But if one wants to beg for it, why not let him do so? It does not hurt anyone and there is no guarantee he will be successful.
If one person is allowed to beg, everyone is allowed to beg, forum gets filled with crap. Nothing is added by begging, it's just clutter in the way of real discussion... like about why begging is bad.
The amount of begging will self-regulate according to its expected success rate. The success rate will diminish with more people begging. So I do not see a problem here.
"Crap" is a subjective attribute.
So is "value".
