There have been many discussions about creating alternative accounts to participate in pizza or pie-baking contests. Alternative accounts will always be made in those topics where it is easy to get a little merit. However, alternative accounts are not prohibited, and people who create them have learned to hide their connections with other accounts very well, so I think that many have checked these accounts dozens of times, and if there are no errors, then there is nothing to talk about.
Bangladesh is a highly impoverished nation, where individuals actively pursue opportunities to enhance their income—like anyone with a very low standard of living. I looked at many accounts, and I can’t say that any of them are breaking the rules. As they say, until caught, there is nothing to blame.
