An email. automated or not becomes a tangible target at which to lash out.
This is not about a 'difference of opinion' or simple abuse...it's about bruised egos that refuse to accept a decision made by another person, irrespective of reason or qualification.
Invariably, the less puerile antagonist will post a 'why me?' thread similar to this....usually after his own ego is bruised.
The fact of the matter is that there is a finite 'space' allocation for wall content on what is intended as a skinning site, where walls are an adjunct and not the prime directive.
Not all walls will be accepted. They will be subject to selection. If an author has a query about the reason for a particular work being removed he can always send a polite email, however, with the large number of works submitted it is quite impractical to compose a tome of detailed post mortem on everything rejected.
More and more I, for one, am increasingly impressed with the 'quiet acceptance' of some artists whose work so frequently does not pass muster, yet neither criticizes nor complains, just continues to submit.
Call him the 'quiet achiever', but he is more deserving of detailed explanation and help than those many others whose waking moments are engrossed in spit and moan...
