This is horrible. This type of experience could discourage the person to ever seek help in the future, whether online or face-to-face.

Unfortunately, online therapy at this time is not well-regulated and so there is little accountability when things like that happen. It's a disgrace because we have Internet for a few decades now and it's long overdue to organize and regulate this modality because it has a big potential to help many people who otherwise would never set a foot in a therapist's office. At this point, if I were to get online therapy I'd prefer to deal with a solo practitioner than a big company like BetterHelp because in that case you can at least verify their license number and check if they are allowed to practice in your state. There is a much better chance that you can hold an individual practitioner accountable than a big company.

What you need to know when seek therapy online is that many states do not allow therapists from another states to work with the residents of their state. Also, be aware that those who practice online are under the same obligation to follow the laws and the ethical code of their profession as those who practice face-to-face. When you deal with a solo-practitioner you can contact their licensing board to check what regulations they have regarding online therapy and to see if the therapist you are considering is following those.
