Hi
Your issue goes beyond a couple of reviews. In your public profile only 164 reviews can be found, and I believe you uploaded a total of 195. So actually 31 of your reviews were taken down by the spam filter.
Try reading Common Review Violations
And
Hidden Reviews? Read this.
I also noticed that you might not be aware of the guideline re duplicate and similar photos. Check this link.
The spam filter is far from perfect. It can take down perfect and authentic reviews while leaving up a ton of fake reviews.
Please take a critical look at your reviews with the guidelines in mind. Fix what you can. If nit successful there is a firm to request a manual check for wrongfully hidden contributions.
