The problem with this Slack Connect is that it's all-you-can-harass. As mentioned above, Slack Connect is a function that sends an invitation email to the email address you entered, but since it was OK to enter any content in the enclosed message, it is possible to send a harassment message. Furthermore, since the sender of the invitation email is '[email protected]', automatic filtering is also excluded, which is a very easy-to-use function.

This harassment issue was pointed out and discovered by users shortly after the feature was released. On the other hand, Slack announced Slack Connect as of October 2020, so it has been criticized as 'Did you realize the possibility of harassing for about half a year?'
Slack has already changed the specification that allows you to freely enter the enclosed message, and changed it to the specification that only fixed phrases are enclosed. 'Thanks to everyone who raised their voices,' he said.
