Welcome - @Wildiris I understand your frustration, you don’t just have the option to block members, you also have multiple options to tap on while reporting items that are violating app guidelines. If you’re seeing a particular violation and there’s no button, you can use the “Other” button informing the OfferUp teams so they can investigate and take appropriate action on those accounts.
Bull I reported a seller 3 times and they were a True member so offer up had their ID on file. This happen 3 weeks ago. There has been zero contact from Offer up. As we all know like FB customer service is just line item on the list of stuff they really don't address.
