Hello,
Thank you so much for getting in touch.
If you have multiple Rank Math accounts, yes, we can help you merge them into one main account.
Please note that the PRO version can only be used for personal websites that you own 100% and not a client website or a partnership with someone. A personal website can be a business, earn you money and you can even sell it to anyone but it needs to belong to you.
We use a few different methods for detecting abuse which is confidential and cannot be shared publicly for obvious reasons.
To help you choose a plan appropriate for your company and to see all the features, you can check the following comparison:

Hope that helps.
