I understand why you think that might be the case, but I’ve set up the community such that you can’t create a post unless you are approved by an admin. Approval here means that your service needs to be vetted before you can post. The whole point is to find quality providers and share reviews, if we allow anyone to post, the community would be overrun by low effort spammers in no time.
Also, see this comment on why I’m hesitant to share the spreadsheet.
