Patch 3.3.3 Deletes Every Username Containing the Letter 'E' — 900K Accounts Renamed

The sanitization script was written to flag and replace names containing characters from a specific exclusion list.

A text sanitization script in Patch 3.3.3 contained a regex error that interpreted the letter "e" as a forbidden character. All 900,000 accounts with usernames containing the letter have been auto-renamed to randomly generated strings. Appeals are open but the queue is eighteen months long.

MIncident Timeline

  • Patch: Version 3.3.3 — username sanitization update
  • Bug: Regex treated letter "e" as forbidden character
  • Accounts renamed: ~900,000
  • Status: Bug patched — appeals queue 18 months long

Patch 3.3.3 was designed to address a separate issue — the proliferation of usernames containing certain Unicode characters that had been used to impersonate other accounts. The sanitization script was written to flag and replace names containing characters from a specific exclusion list. The exclusion list, due to a character encoding error in the regex pattern, was interpreted by the system as including the lowercase letter "e." The letter "e" appears in approximately 900,000 of the platform's registered usernames. All of them were replaced overnight.

"My username was @NebulaExplorer," wrote one affected user in a post that has become a repository for similar testimonies. "I have had that name for six years. It appears on my profile, my community badges, my verified creator credentials, my sponsored content disclosures, and approximately 40,000 archived posts. I woke up this morning as @X7K2-M4N9. I am not @X7K2-M4N9. I have never been @X7K2-M4N9. I would like to not be @X7K2-M4N9."

Regex Error, Nine Hundred Thousand Casualties

The human cost of the error extends beyond inconvenience. Several users whose usernames contained their actual names or long-established creative identities have reported significant distress at the loss of what they describe as a core part of their platform presence. Business accounts whose usernames were part of their registered brand identity have contacted legal representatives. Creators whose names appeared in verified sponsorship agreements are in contract dispute territory that platforms' legal teams are "actively reviewing."

The appeals process for username restoration is operational but overwhelmed. Platform support has confirmed that the queue is currently estimated at eighteen months, based on current processing capacity. Several users have pointed out that eighteen months is longer than many of them have been on the platform at all. MetaCorp has promised to "accelerate processing" without providing a revised timeline. Community members have begun a mutual aid system for documenting pre-patch usernames using archived screenshots, in preparation for whatever appeals process eventually materializes.
