I see your account Last Active: March 10, 2018, 03:09:21 AM.
Based on Bpip there are no changes to gmail or password.
if I'm not mistaken, bpip project began sometime mid 2018 in july/august
the project started recording logfiles since then, so you won't see anything before that
Why don't you, immediately declare on Meta 4 your account is hacked. Lol.
inactivity doesn't always mean hacked, maybe he just doesn't use those accounts
but you did point out that those accounts are connected, and can be assumed/treated as alts
