Sure.
I am assuming we are referring to these two threads (correct me if I am wrong).
One is by Nethaera, the other is by Bornakk.
Nethaera almost entirely has posted “News” topics only. And many of them link to articles/guides. So a post by Nethaera for a guide for the cloak is actually in tune with what Nethaera does on the forums.
Last 4 posts by Nethaera? First Steps into WoW Classic, PVP Brawl : Hotmogu, BC TWing, WoW Classic Class Quests. All posts going to an article/guide concerning the topic. The most recent splurge was 9 days ago.
Bornakk is a bit different. He posted quite a bit regularly up until Jan 24th, posted about corruption effects changes on Feb 6th, then the thread being mentioned.
So neither one was gone for months. One showed up to do exactly what they’ve always done (guides).
So I am not sure I could draw the same conclusion based on that information.
