This is a very serious allegation and I need to know details. Please email me (jgc AT cloudflare DOT com) with details of the site and who you are alleging made such a change.
I sent you an e-mail describing the incident in detail, with a link to the support request I opened at the time of the incident.
I actually really do like Cloudflare a lot, for the record, so I'd be glad if it turned out to be something more innocuous. But at the time, Support said they'd look into it, and I got nothing but radio silence since then.
