If you really have a large user base, and want to convince potential users, then you should do various ways to convince, such as having a verified account on twitter, having a youtube account that has quite positive comments about their experience, or even better, you at least get a good rank and trust (contribute) to this forum. So I'm sure, it will attract the attention of many potential users, although it doesn't guarantee people's 100% confidence, but I'm sure it's almost 90%.
