I'll check that reddit out. Its the NCA involvement that backed me up. And apparently 560000 SARs are issued a year, mostly to law abiding people. I know they're trying to stop laundering etc but to be when the ratio of innocent to criminal is so high its quite shocking its legal practice. I think with monzo being the new kid on the block they may be a little overzealous.
I think these joke banks are going to be considerably twitchier than real ones. There are countless stories of people getting frozen for sending their mates some money or buying crypto p2p through it.
This is the forum you probably want -
https://community.monzo.comhttps://www.reddit.com/r/UKPersonalFinance/comments/8r96i1/urgent_help_monzo_closed_my_account_immediately/ this thread is a little alarming. It looks like Monzo sent money to the people who paid OP for coins through LBC without bothering to check anything. Best to keep a close eye on progress.
