Not really, but I don't think anyone manually deleted the account, so I'm not sure what happened

I don't think either! Well, If it ever happens again you will know for sure :')

Thanks for the replies by the way!

We do not delete accounts for being inactive. Perhaps you didn't complete the registration.

Obviously I believe there was some issue with the registration status, but all three times I did set a profile picture (and a password, otherwise I couldn't set a pic or login).

Is this all or do I need to do something else besides setting a password from the confirmation mail I received?

I don't remember deleting accounts (except for some that posted spam). What were the names of these accounts?

This exact same account "amgi" with the same username and profile picture, maybe it was because I didn't post anything after signing up (?), I hope a fourth time will not be needed :')

Is there anything I'm doing wrong? It seems it keeps being deleted.
