How to find if the trusted members are still the guys we know

1) Vod- use of  smiley
2) SebastianJu- Randomly uses "i" instead of "I" in some sentences
3) Quickseller- Writes in a complicated and long manner which makes it hard for (normal) people to read
4) Shorena- Mostly neutral view and is helpful in techical things
 Let me know if you know of ways of recognizing some other guys
