If you aren't listed on Info Vilesilencer then I'm not surprised. People count referrals, but are oblivious to the fact that most people submit straight off the excel sheet, which will send no referrer. If you rely on DC alone, don't expect to survive.
It lets you know where your traffic (and submissions) are coming from. You can't really judge how much traffic you get from the infosilencer list since a great percentage of them will not list a referrer (because they come from an Excel sheet and not a web link).
mine is directory.wtslink.com for ppl want to sell ( WTS ) their link add now for free next update will be PR5
