Tried to, but they block some vpn IPs and ne some mail domains, notably mail aliases

Plus they basically stopped replying to me. Are mail aliases really used as spam? I believe it’s a made up thing

And anyways, when contacting them manually, it should be enough to understand that it’s not automated. It would be so easy to spam register using non flagged IPs and non flagged domains but they’re still rigid about these rules. I hate when services do that.
