This is very disturbing for ways that some folks might not realize. One of the servers I've leased was assigned an IP address range whose reverse DNS (i.e., PTR records) ended in .ir. I only discovered this because I was trying to use Google's CLI tools and got blocked, with the shocking message that access from embargoed countries was not allowed. I was utterly confused given that my server, myself, and anything to do with my hosting was all contained completely within the US. After studying the message and finally figuring out after some time the problem, I reported it to my host and they promptly submitted a correction to that, and the issue was resolved. But had I somehow used this host to access Slack, I would find my own account deleted, if what is being deduced here is correct. Deleting or disabling accounts is completely the wrong approach. The absolutely maximum that could be done is BLOCKING ACCESS (i.e., actually embargoing) from these restricted IPs. Disabling or deleting accounts is stupid and shows that Slack has a profound MISUNDERSTANDING of how the Internet works, i.e., it's not perfect. This is exactly akin to using an IP address for identification. IP addresses, and hostnames, are not identification of people and cannot nor should be used for these kinds of heavy-handed, punitive punishments.
