Thanks for your query.
My experience and testing is that Adultwork do not currently
link by IP alone.
So you just need to use different web browsers for the different accounts you setup and make sure never to forget which account is for which web browser.
Mozilla Firefox - galinsoga
Internet Explorer - liverpoolpuntingexpedition
Google Chrome - superpunterforashortwhileatleast
There is evidence to indicate (from posts that I have read on the forum) that Adultwork used to in the past link account simply based on IP and that would be inconvenient to get around (possible but not worth the effort) but my experience is that they don't do it currently.
If you ever want to check if your accounts have become linked (which is called an "alias" on Adultwork speech) send a message to the inbox of a working girl friend and ask here whether it shows an alias on your account, if it does then there will be a number next to the number for your feedback showing how many aliases you have.
There is a good write up on what aliases look like on the side of escorts on this girls blog (who has in the past been criticised on here a lot for her high prices and prolific blogging including on Christmas day).https://www.adultwork.com/1239480
