Good try but I don't think that is possible.
And if it was, I doubt that management would take their valuable time to put people on like that.
If a member's profile page seems active, it is.
Now some pages say "this poster is banned or suspended" or something like that when they are actually not banned. The legendary Senator Pardek was the first to do that, everyone else are just copycats.
Some members like to do that to see who they can fool.
It IS possible because I experienced it........
I don't remember that one. I do recall some others, with the best application noticed sending a few of the religion forum posters quite batty with the ruse. It went on for months. He had 'em going BONKERS. By then, that particular code-fake itself was years old(?)
After a while, mercy got the best of me, and I had to ruin the joke and show them how (name withheld to protect the guilty) was just messing with them. It was hilarious for a while, but there were signs of serious meltdown becoming evident. A small crew were beginning to blame FR, unnamed moderators, named moderators, jimrob, etc., with babbling incoherence following, reminicesnt of Alex Jones on a bad conspiracy theory day.
The bonker-est were and are of course, among the dimmest bulbs.
I love those post number whatever and one-half tricks. If it's done just right, it works on several levels at once. Truly delicious.
