version 6.5 is pretty put of date. Currently the topic title field in the database is varchar(255). I suspect it was back then too. Any restrictions in topic length via the form can be bypassed, and there surely was nothing in the actual scripts back then that would have limited it.
In other words, no, it wasn't hacked.
