Is Whole Form Filler - CTH safe?

Low risk

Whole Form Filler - CTH auto-fills web forms and can send canned outreach messages through GoDaddy's WHOIS contact form.

The extension runs on every http(s) page to fill forms in bulk. Its automation can send a preset message offering logo or website design to domain registrants via GoDaddy's WHOIS email endpoint, with the operator's address as reply-to. Its content script also answers page messages from any sender with the frame's localStorage values, without checking the sender's origin.
