Why do Mods Lock/Delete my threads, but leave trolling threads up?

[Imaginesafety]

I just posted a thread that did not fall out of the guidelines, yet the mods lock it. If a mod happens to view this, can you please explain why it was locked? There are so many bashing threads, and trolling threads about new scans, but they are still up. So unfair. My thread:

You must be registered for see links

I wasn't even bashing anyone, smh.

It could've been posted in the pairing sticky.
