While that is true, the making of the resource unuseable to the people for which it was set up does, in fact, fall under “DoS” terminaology.
I have the printout somewhere.
It is not the “classic” Denial of Service you come to view as thousands of bots sending millions of messages ito a server or corporation or whatever.
One quote: "Network attacks include outright floods of data to overwhelm the finite capacity of your connection, spoofed unreach/redirect aka “click” which tricks your computer into thinking there is a network failure and voluntarily breaking the connection, and a whole new generation of distributed denial of service attacks (although these are seldom used against individuals unless you’ve really upset somebody). "
It’s been and being looked into.
Whatever you call this, it killed the ability of the normal user to enter and normally use the forum.
While you are correct that normally we think of these as network or IRC attacks, anything that removes the functionality is considered a DoS, albeit a fringe element thereof.
So, I suppose we could call it:
A concerted effort by someone who set up the software and “bug” to exploit the limitations of the PhP BBS and deny the users the ability to normally use the service.
That makes it a “AcebswutsaBtetlotPBadtutatnuts”.
Easier to say “DoS”.
