Related, proofpoint is notorious for this as well. They will block your mail server without cause, forcing you through their process of delisting.

Pay and your problems magically go away. Proofpoint was consistently the only block hit.

Tbf putting up cash is a great signal for 'not a spammer'.

True, but not the only method. You’d be surprised how many spammers drop with greylisting enabled.

Not really it's just a cost of doing business and if paying that cost "legitimizes" you then the ROI is probably significant.

Similar to a mafia coming to your small business and telling you you need to pay to stay open, otherwise they’ll make sure you. Still just the cost of business? Seems more like a power imbalance.
