This place is crazy... like an old leaky boat in the cartoons where they keep patching holes with pieces of chewed gum and plugging fingers into a hole just for another to open up again. Just band-aids on top of band-aids while the system as a whole slowly loses its wheels one by one.
In this case I would suggest contacting the thread owner as it states in the screenshot...
Since the current designated thread owner, inforfront, is not staff, all that will result in will be a few of the most offending posts getting deleted. Since infofront is not staff, no other accelerated action can be taken. Since infofront is a volunteer, many of the offending posts can persist for hours, days or overlooked. By that time, more likely than not, an argument has already ensued and the damage is done. Also, infofront cannot be too heavy handed in the deleting of posts. Otherwise bitching of infringing on "freedom of speech" ensues.
I know the arrangement for this thread appears a little odd. What happened is that the original op of the thread became inactive. It ended up becoming a great deal of work for the staff to moderate, so theymos locked it. However, the thread is quite popular and members wanted the thread reopened. So theymos unlocked the thread and appointed a new thread owner.
Overall, the thread is a bit lively. However, then realr0ach comes in and shits in the pool.
