Now that's something I can't find any excuse to exist even though I find no rules to be the best rules.
Maybe the taste is not bad, but it looks very recently alive and that's an amount of mayonnaise one can use to dress a bucket of vegetables. Well, not really, but I don't think it's a healthy amount to get in one go for sure.
What concerns me more is vinegar in mayo and the rest of contents a bit. I'm not against fats if it's butter, or olive oil, or some such. But mayo is just something too meh for me
