Re: Bitcoin Address Balance Checker (Web) - Check balance of addresses in a browser
Can give me more details about your configuration? which browser are you using? Tor? Are you using any VPN?
I used Tor Browser. There's not much more to add 
No VPN.Quote
I could do something like that. I would request all those matching addresses from your database and then i would locally (with JS) filter those address and display only the requested ones to the user.
Just thinking out loud: you could make 2 input fields on the site: one with real addresses, and one where the user inputs funded addresses they don't own. If this is all handled client site, and all addresses are requested from the server (in no specific order), the "dummy addresses" can be ignored and only the requested addresses are shown. It wouldn't be perfect, but I think it can be called "improved privacy".Quote
I know how to request that to your server, but I need to study more to know how to create a database which would accept requests like that in your server. I don't know if it is possible to do that with a txt file
