The club received a "significant fine" as a result of fans using flares and smoke bombs at major matches. I hear a few bannings are planned.

I'd count myself as one of those who dislike flares and the like, on many levels, though I wonder about the FAI/LOI's record at tackling them evenly across the board. As for bannings, I'd have thought "offenders" could just be be put on a final warning footing.
