Call me a little work-shy here, but I'm not going to attempt to justify any of the concerns brought up in this thread just yet. Most (if not all) of the factors that people have brought to the table - from concerns regarding complete and utter overkill to moderator bias - are completely understandable, and to toss them aside would be a half-baked decision to say the least. However, to act solely on conjectures wouldn't be the best move in the world either. While I can't speak for the other moderators or administrators, throughout the next week or so, I'll be working with the new mods to make sure they delete content only when necessary, ask the rest of the team when they find themselves uncertain as to whether content should be removed or locked, and ensure that they don't go around deleting posts out of context, consequently causing another jimmy rustling session like we've seen today.
Personally, I find posts such as these to be perfectly fine, and I can completely agree that small light-hearted posts are fine to stay. It's only posts that contribute absolutely nothing to a given conversation that I give the flick, such as your stock standard "lol", "this" or "tl;dr". Admittedly, the line between content that's considered acceptable, and content that's deemed out of context tends to become a little grey as the number of individuals moderating the forums increases. Conversely however, now that we have focused team available to compare and contrast their opinions on content, we can aim to have collective decisions made about what stays and goes, as opposed to relying on a single individuals discretion, which more often than not leads to some rather thorny difference of opinions.
Everything considered, it's still early days. Just like our first batch of moderators, please be so kind as to give us a few days to a week to get everyone settled, on the same page and working with each other, and if we're still having major issues, we'll work openly from there.
