Along with Bitcoin spam transactions they're also trying to make emergency adjustments to BCH mining difficulty while they pump BCH price. They also have "BCH much wow" sockpuppets roaming the web talking up to coincide with pump movements.

It's not something that's sustainable, they can only do it in burst and each burst gets more pathetic as the cryptocommunity wises up and tells them to fuck off.

Transactions will clear when they've burnt through too much money and give up, there's also only so long collaborators like Shapeshift can justify putting a hold on Bitcoin transactions.

Take note of what all of these people are doing now, remember who betrayed and tried to manipulate you when the dust settles.
