You can try, but you may risk having BWS reset your post count to zero...
the admins dont like spamming to reach specific post counts ...... as mentioned above they will reset you or make it dwindle each time you get close
so the best thing to do is to participate in normal threads (please note do not post one liner replies which could be construed as spam)
and the worst part is, now that you have made this thread they will be watching you like hawks to see your next move which i suggest should be a sharpish apology and then continuous posting in a normal manner showing participation in the forum ..... otherwise you could find your post count dwindling even though you keep posting
one more note posting in the classifieds does not add to your post count for the purposes of being able to use the classifieds .... hence you will need 50 posts in all other sections of the forum before being able to use the classifieds
