looks like they closed down their slack
Dear all,
Despite using the most restrictive settings for our Slack channel (a discussion website which was being run for the Tezos community) scammers were able to take advantage of the unrestricted webhook functionality to trigger Slackbot into contacting every slack member with a phishing URL.
The safest option for us, at this point, was to shut down the Slack channel completely. We imported the email addresses of Slack participants into this mailing list so they could be informed. We will resurrect a channel in the future, hosted directly on tezos.com.
In the meantime, as a reminder, always access the tezos.com website by typing in tezos.com directly in your browser. Do not follow links, even if they look like they point to tezos.com or if they look like they came from the Tezos team.
