Nexo uses Sumsub for KYC
Hi, I was a verified customer with Nexo many years ago, but after re-login to Nexo it asked me to re-verify my identity. I questioned why but they insisted without giving me a reason. After I completed the Nexo's 3rd party provider Sumsub's verification, the screen shows "We couldn't verify your identity." I was pis*** off. Because the root cause is from Sumsub, therefore I wrote an email to Nexo saying I'm going to make a 3rd complaint to the Information Commissioner's Office UK for Sumsub and you need to manually verify me. Just before I finished writing the email, I received another email from Nexo saying I was fully verified. And also the Sumsub screen refreshed with "You've been verified." I don't know if Nexo manually verified me or I've been whitelisted by Sumsub. Because I'm verified, I changed my mind to complain to ICO UK about this time, and leave a 3 star rating for Sumsub. I used to leave 1 star rating, but I'm a fair person despite the trouble caused though I ended up with a satisfactory result. However I will leave a 1 star to Nexo for asking a fully verified customer to do kyc again.

I appreciated ᗩᴜʀᴇᴀᴛᴇ Rᴏᴜᴛᴇ’s clear and honest communication after losing money to this company . They avoided unrealistic promises and stayed transparent. Their efforts paid off, and my money was returned.
Did they just try to take over my subreddit?
sketchy af. dont use! Gallow logic: Sumsub verifies your ID but can't verify a modmail convo exists before begging Reddit for subreddit control. 😂 Tried sneaking into r/Sumsub via r/redditrequest with a phantom "product chat" link that 404s into nowhere—no prior contact, just vibes. Claimed we "block tech talk" while we host real user complaints about endless rejections and data risks. Reddit shut it down per rules. *If* they (possibly) lie this sloppy to own a tiny complaints forum, imagine what happens to your selfies, passports, and bank info. Hard pass—steer clear.
time wasters
We stopped using it for our own business (KYC) as they continued requesting documents from us after we made payment, and whatever we send, it was never enough: we never got out of the sandbox status and could not use the system. Much better systems available. Now I also used it to get our company through KYC: iot doesnt accept our address ... and I know our address exactly. Just dont waste your time with this system, they dont seem to know what they are asking and then will reject your customers.
