Just saying, but every forum I am on has that stat of the number of messages posted, and it is visible to everybody. I could call you a loser based on game stats so should we not have that too? That's a silly reasoning, and plus this was never meant to be a general statistics topic.
I stand by my suggestion, although I know I mentioned it before. Give the people the option, put a checkbox and leave it there. Lots of sites have it, and it works well.
For the stats about your number of posts, there are two reaspons why I didn't put the information under each post, as many forums do:
Our general goal on the playroom is to make pages as friendly as possible with screen readers and that includes don't clutter with information which is 99% of the time totally useless
It may encourage some people to spam or do post race, i.e. I have more posts than you, or hello this is my 1000th post.
This example about the number of posts agreed not important but was making an example. I have seen much more sinister abuses of the statistics.
The I have seen doesn't identify what is the issue that's been seen
