Slack apologizes after users who travelled to Iran had their accounts shut down
- On Wednesday, many users who had traveled to Iran found that their Slack accounts shut down because of U.S. sanctions, even though they did not live in Iran, nor did they have professional links to Iran.
- On Friday, Slack sent out an apology to its users and clarified that it did not have information about users' ethnicities, but used location information.
- Slack is working on restoring mistakenly blocked accounts and will soon start blocking accounts with IP addresses in an embargoed country.
$7 billion workplace chat app Slack apologized on Friday for mistakenly shutting down the accounts of several users this week in its efforts to comply with US sanctions towards countries like Iran.
Slack said that it uses location information such as IP addresses to block users from countries affected by US trade embargoes and economic sanctions, and that in doing so it "inadvertently de-activated" the accounts of certain users. The company did not specify how the mistake was made, but stressed that it did not block any users based on nationality or ethnicity.
Earlier this week, several ethnically Iranian users tweeted their concerns that their accounts were abruptly shut down even though they didn't live in Iran or have any professional ties to the country. One PhD student in British Columbia wondered on Twitter what Slack's basis was for determining his ethnicity.
"We do not collect, use, or possess any information about the nationality or ethnicity of our users," Slack said on Friday.
Several of the affected users had said they recently travelled to Iran, which may have caused Slack to flag their IP addresses.
Slack said it's working on restoring mistakenly blocked accounts, and apologized for not handling the communication well. The company also noted that it will soon begin blocking accounts with IP addresses associated with an embargoed country and said that users traveling to a sanctioned country may temporarily not be able to access their account.
