That wasn't a reproach, I won't expect anyone (even with the announcement thread) to have the time to test every mods out there.
Back on subject, the mods ingame should mostly be safe, but without a comment system, that'll never means 100% safe. Waiting a bit to see if there are bad reports on the official forum or here for new mods from unknown modders, or using only mod that have their own threads would be my suggestion. (and having an up to date AV, even if that's not related only to downloading mods but just downloading anything)
