Alternatively, they may not really be her posting with those accounts, and she'd been forced to "verify" them with Kim to make them more credible.
In a Tweet that I can no longer find, Kim Silvio said she did a quick video chat with Dijana to confirm the new Twitter account is in fact Dijana. About 10 hours after that tweet, Kim Silvio said she is 100% done with all of this as both sides are playing her for a fool. Obviously she doesn't like being told she is the enemy until she is needed and who can blame her.
Something odd is going on in the JLE house. Somebody pumped Kim and Mikey with info for 7 years that knows the inner dealings within that house. Until shown otherwise, my belief is "Marko" lives in that house and has been playing us for fools.
