I haven't seen recent inconsistency, I must admit, but I've been busy for the last couple of weeks and haven't read a great proportion of what's been posted - so if there are specific instances of over-or-under moderation that you are not happy with please feel free to notify the admin team. We can't always keep up with 100% of what is posted so keeping the forum consistent is partially down to to originators of the content, not just those who moderate it!
IMHO there are probably 3 categories of words:
1) Those which we absolutely won't permit in any context.
2) Those which, depending on the context, may be seen to add colour, impact or humour in some contexts and unnecessary profanity in others. They may be inoffensive when used in general but highly offensive when directed at another member or a minority, for example.
3) Those which are OK in all contexts.
Most "colourful" words on the forum fit into category 2. This means that context is very important in most decisions we make when moderating, so the decision is not a black and white one and, whilst we strive to be consistent, what immediately rings alarm bells for one mod might be missed by another.
We all know "the shed" and, therefore, an example of what happens when standards aren't applied at all. I hope the majority of us prefer the status quo?
