People ... If I may step in as "peacemaker" here,
I know "Cymmon" personally, he admits himself that he is a "spotter" but he just happens to be a spotter that flies business class and regularly more than once a year and often long haul.
Should his question have been posted in "Nostalgia" or "Spotters"? ... Well I'd suggest it should have been posted in "Spotters" but that's something of a grey area as biplanes are also "Nostalgia".
Now if his attackers, one or more that might have joined only a month or similar ago, then it sounds to me like there are spotters attacking spotters in "Nostalgia" rather than "Spotters" so it might be said that you're all as bad as each other.
On the other hand, if one is an aviation professional then "Cymmon" is likely to be contributing more to your salary than one's average "bucket & spader" so I'd suggest that one should be ashamed of oneself attacking one's clientele whilst hiding behind a keyboard or keypad!
