Is it against the rules to comment on my own review to
move it up the page?
There is a Guideline against Bumping a Review more than 30 Days old.
Other than that, no there is not a Guideline.
However, doing so is bad form and could/would result in scrutiny from your fellow Members.
Additionally, you open yourself up to being seen as a promoter.
Once tagged as a promoter, Members tend to discount your reviews and Staff starts to regard your submissions as advertising.
Advertising is not permitted on Eccie.
Good advice, don't need my form to be any worse
