A complete spamfest by examplens, tranthidung, dkbit98, hugeblack, bitmover, Stompix, Rikafip, Igebotz and BlackHatCoiner? Yeah sure. And every day new users are teleported.
Asides from my teleported message, I have never submitted a single post!

And yes, the rest are quality posters, but they're a really small minority.
Did all the posters you mention "defect" from here to there? If they want to post over there as well, good for them, but I'd be very surprised if they stopped posting here.
As an aforementioned user, I can assure you that altcoinstalks is a spamfest. Having "Coin Voting", "Bounties & Rewards" and "Aidrops & Giveaways" as the very first sub-boards visitors will immediately see, says it all.
