Da Vinci code from habr?

Question

Habr

Wrote a post, looked at the preview, sent. Looked again - everything is fine. Then I saw it in the feed, and there, at the beginning of the post, an incomprehensible code:


I opened it for editing - it's there. Ster, saved. Again, the same rubbish, not on the preview, but appears in the post, but already a new one.
Is this a bug or a feature?

Answer 1

Similar to unixtimestamp

Answer 2

Disable all plugins in the browser (create a new profile/open Habr in another browser) and try editing again. Some of the antiviruses added such garbage to my requests through a plugin.
