I kinda solved this problem for few accounts, what i did was this :
1) Used 3G/4G tethering to my computer
2) logged in chrom INCOGNITO in the infected ig account
3) verified it by email
4) pressed "verify" in massplanner, went back to the chrome incognito
5) the browser showed this :
View attachment 83847
I chose "It Was Me"
6) account status on massplanner : VALID
did some follows and still valid.
Here you go, i hope this was a good solution, and accounts won't get back to the email loop again. But we never know
