Questions, corrections and takedowns
tokenusage.dev has no public issue tracker of its own. Use the one for the plugin that feeds it: token-counter's issues on GitHub.
Issues there are public. Never post your share token, and leave out anything you would not want anyone to read.
A question or a correction
Say which page, what it says and what you think it should say, with a source if you have one. For a figure that looks wrong on a profile, give the handle and the day or month.
A takedown
Handles are self-chosen and unverified, so one can impersonate someone. To ask for a handle, a profile or a report page to come down, give its address (such as tokenusage.dev/u/<handle>) and why: whom it impersonates, or what on it should not be public.
If it is your own share, you do not need to ask: the plugin can delete it or take the report page down at once. Privacy has the commands.
A lost share token
The token from your first share is the only proof that a handle is yours, so a share without it cannot be updated or deleted from the plugin. Say which handle, and what you can about it. To start over under a new handle, run python3 scripts/share.py --forget first: it drops whatever token the plugin still holds on your machine.
