This Monday, March 3, many users had the unpleasant surprise to find themselves blocked on Leboncoin and several merchant sites. In question, a bug from a security operation preventing access to their account.

Panic on the internet! This Monday March 3, 2025, shortly afternoon, many users reported on our forum And on social networks that they could no longer connect to the site of classified ads between individuals Leboncoin. Some Internet users were indicated that their account had been blocked while others could simply not connect to the site.

But it seems that the classified ads between individuals is not the only affected platform. Indeed, on the DowndeTector specialized site, many internet users report dysfunctions on e-commerce sites and applications, such as Vinted, SNCF Connect, FNAC, Darty, FDJ, Leclerc Drive … Again, users are found with their blocked accounts.

All these sites require an unusual verification. “We make sure that we are talking to you, not a robot (…) Why this verification? Something in the behavior of the browser has intrigued us”can we read. The message explains that this bug can be linked to “Several possibilities” : either “You surf and click at a superhuman speed”either “Something blocks the operation of JavaScript on your computer”either “A robot is on the same network as you”.

According to some Internet users, it would be due to “An anti-robot system” failing. Fortunately, things have gradually returned to normal from 1:30 p.m. so if you ever meet this problem, wait a little and try your luck later in the afternoon!
