Legit ad or suspicious?

Found this ad-link on a non-malicious Dutch website: -http://r.ligatus.com/?z=u11tb9MdDz_AYd9-jDJsEI8Q0gg5Lw0rreCiK5JIh2g_Fr3Ed8bnn_WafdylI-WHE1Ki4eKqSozmLqqNdmG5Xjb8X7zMlA7hYE6SOD8iQlJEOQJA9eNqMFj7wT10yCC4hPuOT1QUxerXuCY6in4QK_JAAnZztrot_f5Szw

Good that came blocked by an adblocker for me. Automated self-learning ad-launcher, but as it seems above board and not malicious per-se, still better blocked by uBlock Origin for me.
