How come so & so can post XYZ, but mine got deleted?
It's true. This does happen now and again. And your keen eye has picked up an inconsistency, after all you're probably pretty focussed on it at this point.
Hopefully you realise there is a collosal amount of posts, and it's a massive task to keep on top of who writes what and keep it all clean / within the forum policy.
Just because a similar post to one that you wrote hasn't been removed doesn't mean "we let that one go, but targetted you", it generally means we've not seen the other one.
Let us know if you feel you've been hard done by. Ultimately, the goal of the forums is to create a friendly place and a great community vibe!
