How can I prevent spam reviews?

We just got a review from a strange email with a bunch of swears. Is there an IP?

We are actually starting to get attacks from counterfeiters of our brand that are ripping off our stuff. So we see things like this and think it is related to that. I am open to suggestions on how we can protect our product reviews from malicious things like this.

To prevent spam reviews, you can:

(1) Restrict web reviews creation, including turning on the "Heavy restriction" so the spammer can no longer create a bot or code to programmatically create fake reviews.

You can find it in Settings > Review Widget > Review Curation > Web Reviews

Or click on this link https://judge.me/settings?jump_to=web+reviews 

• Restrict review creation: This hides the “write-a-review” button so it is not possible to leave a review via the widget on the website. Reviews creation is restricted to (a) verified buyers from our review requests, or (b) programmatically via API.
• Heavy restriction enabled: In addition to the above (“write-a-review” button hidden), API requests are also disabled, so spammers with bots/code that target shops will not be able to create fake reviews.

(2) Turn on the web reviews spam filter so that Judge.me will detect and filter out spam reviews from Web and API.

You can find it in Settings > Review Widget > Review Curation > Web Reviews Spam Filter

Or click on this link https://judge.me/settings?jump_to=web+reviews+spam+filter

• When you enable this, Judge.me will detect and filter out spam reviews coming from the "write-a-review" form on your webpages as well as via API using a third party spam filter. 
• You can use this setting to filter out spam if you want to continue to allow review creation via the web and API (so if you want to be less restrictive and disable the two settings above).
