Generally, when posters of this forum become unhappy with things like over-zealous bumpers, we tend to speak up. I haven't noticed anything out of the ordinary. It seems only those who's [whos, whose? I never can get that one right!] actions we cannot discuss here, are having difficulty with the bumpage. *shrugs*
It doesn't really bother me, as I tend to respond to a poster in the rare event that I have a sale or auction thread. I will say, however, that person who kept posting pics that said 'bump' over and over and kept changing the title of the original post, was VERY annoying!!
