Simple tool to check if list of usernames (bulk) is available on both Discord and Twitter.
Apologies that Discord part is a bit slow but IDC to make it faster, gets the job done for my use case.
Discord part uses: https://github.com/Lixqa/DiscordPomelo.
Twitter part uses: Official API.
Praise be to the creators of above tools.
For Twitter you need Bearer token from the Twitter developer portal (free version is enough), put into .env file, .env.example as example.
For Discord you need patience.
