Yes, you can get credit without revealing your review or identity.
For each of your pre-publication reviews you are able to choose:
- Content display: hidden or publicly available
- Privacy: blind or open 
- We verify your reviews regardless of what settings you choose.
- Reviews with content that are publicly available receive two additional merit points.
- While we give you full credit for reviews of unpublished manuscripts, we don't display any details about the review (details here).
 A blind review means you select the 'show journal', 'show publisher only' or 'do not show' option and an open review means the show 'journal & article' option is selected meaning the article reviewed is shown on your profile.
