On Steemit, the reputation system is primarily influenced by upvotes and downvotes, not by comments directly. However, comments can indirectly affect your reputation if they receive upvotes.

If you're asking specifically about the impact of comments without any upvotes or downvotes, then comments alone do not directly increase your reputation score on Steemit. Your reputation score will only change based on the voting activity (upvotes and downvotes) on your posts and comments.

To summarize:
- Direct Impact: 0 comments will increase your reputation without upvotes.
- Indirect Impact: Comments that receive upvotes can increase your reputation, but the increase depends on the upvotes, not the number of comments themselves.
