I was forwarding Google Voice SMS messages from a second account so I could remain in contact with old friends (I ported my number I've had since high school). The only reason I had to create a second account was because I switched to Google Fi, which forbids your main account from also having a Google Voice account. Apparently actively using this service does not count as an "active login", because that account was disabled and my number was given to someone else. I only found out when a friend showed me screenshots of my number texting them "who is this?", despite having my main email and phone number as backups for the second account. I cannot get that number back, and support was no help.
