From what I understand....without being in favor of anyone.
Royse contacted theymos asking to look into Jambler, theymos did it and banned the site on the forum. And royse asked one more manager to look into it and I don't want to get trolled so I am not trying to guess who it was and it doesn't matter.
Icopress lost a campaign that was dear to him/her and is trying to see if it's possible to save Jambler on the forum (it would be hard to do so)
My take on Jambler:

If you take a look at the diagram of Jambler then you'll clearly see. (It's classified as a Mixer)
2* Letter of Guarantee is issued by the Jambler themselves.
3* & 4* Jambler is responsible for sending and receiving the coins from the Customer, and
Partner MIXER doesn't even hold the funds.
I don't think theymos will ban icopress since the Jambler was under the radar as to how it works and no one took a close enough look like Royse did (For some reason he thought he had to)
I think many will blame Royse for that and the other campaign manager, who is anonymous atm.
That's all I have to say for now.
Peace~
