Is CDA Downloader safe?

Medium risk

CDA Downloader opens short.ovh tabs during most CDA.pl link clicks and some download clicks.

On CDA.pl pages, CDA Downloader hooks ordinary link clicks and the download button, then opens one of three hardcoded short.ovh URLs based on random chance. Those new tabs receive browser navigation context such as the current page URL and referrer when they open.
