Hi, the website is telling us that your account and https://pokemondb.net/pokebase/user/TaxiDriver
are connected. Could you please confirm whether this is correct?
You should read the following thread: https://pokemondb.net/pokebase/meta/12184
In short, if you're physically related to another person on PokeBase, then you are not allowed to vote their posts or answer their questions. If both accounts belong to you, then you must pick one to continue with, as you may not have two.
Thanks for reading -- please reply when you are able. I will send the same message to the other account.
