I don't think there's a need to remove the negative tag because it will be difficult to have a satisfying response from them which should be regarded as a valid reason. It is worrisome to see Seedcheckpro promising offline check without giving a full explanation on how they intend to provide an up to date UTXO set or even a legit method to sync a UTXO set offline. There's no way SeedCheckPro can begin to promise you an offline check of your bitcoin balance in real time without syncing with the updated version of the blockchain mined online unless if they only want to allow you store your old UTXO set locally which probably gives you the ability to view your past data of bitcoin balances offline, anything outside that cannot be achieved offline for the singular reason that you need to have access to the internet to be able to access the latest UTXO set.
