[Q] Why do threads get locked at 500 pages?

[The Transhuman Union]

Just a question I was wondering, if it is the right place to put it.

Basically, the longer a forum thread gets, the more strain it puts on the server whenever someone loads it. Things start to get wonky with super-huge threads, so we set the cap at 500 as a reasonable compromise between server load and thread length.
