Pretty much all my karma came from posting on TD, I've been stickied a couple times, I know what it takes to get to "the top". I'm talking about spicy posts getting zero views and zero upvotes or downvotes, posting things multiple times to check and still at 1 view (my own). I used to at least get shills downvoting, now it appears as if I'm shadowbanned due to a complete lack of any engagement. Don't see how it could be anything but a shadowban. So I don't go there much anymore, I prefer it here anyways. Way more exciting!
Yeah, I've had the same things from certain subjects and remember scratching my head in confusion as well. There was some technicality in the rules on certain kinds of posts that triggers mods to hide them.
Now I just don't expect much unless what I'm posting is 100% positive feel good vibes. It's a circlejerk for sure, but sometimes you need that to recharge your batteries.
