If you know an SP knows your MERB handle or when you're going to post a review and it's going to be obvious to her who you are (If she's on MERB of course). Does it affect what you write in your review and does it also affect what you post about any other SP's or any other subject on MERB for that matter.
It personally doesn't bother me and doesn't affect what I post anywhere else. I am honest when I'm with them so I see it as another way they get to know me, good or bad. I also enjoy it when SP's comment on these forums it gets to show us a bit of their personalities.
