hi,
i started simple site 23 days ago ,bloggersmosaic.com something similar to milliondollarhomepage, its like 2008 version.
the spam thing is, everytime i go to forums linkshare section, post asking people to review, or talk about for free 4ever spot (i have 250 free spots)
i find someone contacting me, saying its like spam ???
plus other thing and correct me here i used to c reply to posts like this

"gr8 post,thanks
mike
dfsdgdfg.com"

is this now consider spam when you leave signature?

and if you comment on someone blog ,who doesn't have site link ,is it ok to say

i like your post ,kool blog

bloggersmosaic.com (n't link?)

will someone answers my wonder ,because i don't wanna end with spam reputation,
