They definitely have! And muse troubles keeping you from playing makes absolute sense, so I hope it will work out better for you now.
A very recent example of holding back in general would be Hideki's post, I think. You updated on plurk mentioning how silly it was, but the post itself seems rather tame, considering it's him. I understand not making things entirely perverted, but he was barely even glancing at magazines that weren't even that sexual in the first place.
As for the missing clues, it would make sense if it's simply that you missed them yourself! Something might seem obvious to the other player but it could not be as obvious in an actual tag, hm. If you get distracted when tagging, you could try re-reading back a few tags in the threads to see what was going on, just to make sure you're keeping up with it. Trying to keep in mind who does have secrets and things they hide could help, as well. You'd pay more attention to little hints and clues from them that way.
