Apparently some mods tend to delete posts silently if the conversation goes mad but they still don´t lock and exile threads like this one that had no right to exist from the outset. Really, it would be the least to just leave a short message that something was deleted and why to avoid any confusion, suspicion and anger that might happen in consequence of such practice.
There's really nothing wrong with this thread, although we do get these "recommend a pack" threads often they do seem to feel kind of spammy to those of us who are here regularly. But, there's actually no rules preventing them from existing.
..but, having said that; The mods have a "Moderate in the background, silently" policy, basically we can't discuss the reasoning behind removing posts, although we can explain ourselves if we lock a post. I assume the reasoning behind this is to allow the removed content to "die" without people asking additional questions about it.
So really about all I can is some posts were removed, I can't tell you why, and that I was not the one who removed them.
It really depends on your tastes in textures and what you, as the player, want to use the most. A lot of packs on this forum have tags that tell you the overall style and feel of the pack, so it might help looking at those.
I mostly use my own pack (link in my signature ), but I also really like vonDoomCraft and Rise of Tredonia. Rise of Tredonia isn't updated to 1.6, but if you know how to and you aren't afraid of a little work, it's well worth it.
