No way!
It really must be a coincidence.
When looking at different "rooms" I only go through the first page or two before moving on. Consequently if many have been listed they will move beyond that quickly and I'll probably never see them.
Often times I do post short comments on pictures others have put up, but it's because the picture or something about it has caught my attention in some way. Never do I post just to increase my postings. If someones hard work catches my eye, I think I should let them know their talent is appreciated!
Hang in there... :D
