There have been numerous, widely varied reports of legitimate businesses having their funds completely frozen for an unspecified amount of time - often long enough to sink a fledgling startup - simply because they were new and "made too much money too fast".

Payment processors have also been known to discriminate against perfectly legal businesses for a long list of random things some old jackass in a suit decided were too 'unsavory'.

I think these organizations are wrong to meddle so much rather than being passive facilitators as originally envisioned. They have a right to exclude things which put their assets at risk, as well as a legal obligation to assist law enforcement where appropriate, but beyond that neutrality and privacy should be the rule.
