Brin, as a moderator you should be able to see who reads the threads on this site. Take a look, it's at the bottom of the page. You will see that nearly all the threads are read by nearly all the regular posters (with some exceptions on O/T threads). There are many RUFC football related threads that have been running for months and have been read by 50-75+ posters. You will notice one name is conspicuously absent from most threads except for the ones where he 'throws bombs'.
IBS is not an RUFC fan (if he was he'd be reading all the RUFC football threads). He's just a troll (probably a fan of a rival team) who pops in here to wind people up. The only other explanation is he is a multi who spends the rest of his time logged in here under a different name. Either way, the sooner people just ignore him the better.
