I strongly believe that admin needs the ability to verify its users or there needs to be more optional limitations for moderators, such as they should not have the ability to delete anyones post or move it this should be an optional choice permitted by admin.
The main reason why i feel there should be verification for certain users is to improve safety and service between customers and site owners and staff. For example my website is based on people booking a personal trainer for a class or one to one personal training session. My trainers are likely to use the forum and post anything in relation to what they do however someone can impersonate one of my trainers post a photo and link to their own page pretending to be one of my trainers meet the customer or even steal money through faking an account on their own page. Yes if admin is aware they could delete/block the member however if this goes unnoticed then it would not be hard to get away with especially if their site looks convincing enough, however if users know that there are two member types such as unverified and verified it would help a lot for example orange tick for staff members and green for verified customers/members which admin and moderators can deem what customer is deemed genuine through their own process of identification such as an email of electronic copy of proof of identity e.g. driving license or simply holding a piece of paper with a name, or invitation acceptance by filling out a form etc (just examples)
This could apply to Hair salons. Scenario someone pretends to be a hair dresser for the site with the forum they post a beautiful hair style says i am fully booked but go to this link and i'll fit you in privately, tells the person they will meet them at their place and doesnt shows up or does! Direct messaging is definitely needed and find a member by location would help in regards to building a community around your site which becomes a lot safer through verification
