If you’re working with them I’d like to highlight that if they have a messaging platform with children on they are going to have to take safety extremely seriously. I know the laws in the uk are not popular here but the checklists of risk assessments are worthwhile doing - cases where people can privately message children are really high risk because you’ll get a bunch of people who really want to message children. If users can send images you’ll have CSAM to deal with.

That "job offer" tells me everything I need to know about this guy. Cheerfully dictating what you're going to do as if it's a great opportunity for you, with an obvious ulterior motive. Just "you will start tonight!", without so much as a mention of pay or availability, and oh by the way take your post down. Lol.

I used to meet clowns like this all the time when I freelanced years ago. Back then they called themselves "ideas guys" and liked to make you sign an NDA for the privilege of hearing their braindead overplayed product idea. Scumbags and users, every one of them, always looking for a shortcut to personal gain.
