Sir, I think there's only so much even monitors can do. He continuously creates new IDs, and he generally keeps low in the early days. It's only by chance that we can identify him in early days. His original ID is active now, and meanwhile, he has made a new ID. Gives him an advantage to continue his misadventures from the moment his original ID is taken down.
Later on, his blogs and the way he interacts with people is typical and you can easily point him out. It's not that he...
more... only does anything mischievous himself. He usually promotes other people doing nonsense activities on the site. When asked what's the source, he just says IMO, my sources, AFAIK, these are his favorite keywords.
Latest example being, when the news of Purushottam being degraded to M/E was being circulated, he edited a timetable of 2004 and started spreading that time table would be slowed, etc, etc. I think it was you only, who caught his act and then he stopped.
IRI was a treasure trove of information, and a lot of the knowledge I have about railways is due to IRI. But now everything is colored in political hues. People can't take criticism, neither they have patience to listen to other's thoughts. If I say something I'd surely be labeled the supporter of one party or other. It's a state of dystopia.
And as Sachin and Rohit said, he used all his slack after his Coromandel stunt. But sadly he was given immunity, kept active until many days after the incident. After the outrage he was kicked out. But returned as DG Sreerampur and everyone forgot his deeds. What's worse is that the new members engage in his cheap stunts thinking he's a genuine guy.
