Text repeater

Repeats your text as many times as you ask, either on separate lines or run together. Capped at ten thousand copies, which is well past anything useful and short of freezing the page.

The obvious uses are testing and filler — checking how a layout handles a long string, generating sample data, or padding something to a length. Worth knowing before pasting the result anywhere public: repeated text is exactly what spam filters and platform moderation look for, so a repeated message in a chat or a comment is among the fastest ways to get an account rate-limited. The separator field is the useful part for data work: setting it to a comma turns one value into a comma-separated list of a known length, which is handy for building test fixtures.
