by clicking the report a problem button on your profile page and explaining to TER what it is you want them to do and why.

 
Generally TER is all in favor of linking a gal's reviews all on to one profile page, and they will list it with multiple names also.

This is a Q that Admin ("Contact Us") can best address, so contact them. They might ask:
.
Do you still have access to your former account? Is "Milf_Michelle" a new TER account? You previously had a different account "Not_Yet_Milf_Michelle"? If you can log in to your former account, you can then prove that you are still you by sending TER a "Contact Us" from that account, too. (But you're not supposed to have more than one account, so you'll have to straighten that out.)
.
If you have an old account "Not_Yet_Milf_Michelle" but can't log in because you forgot your password, can you still access the associated email for a password reset message? Then, to avoid having two accounts, you can ask TER to change the username on the OLD account. E.g., change "Not_Yet_Milf_Michelle" to "Milf_Michelle" (after the second account is removed).  Well, you can change "Not_Yet_Milf_Michelle" to almost anything you want; it doesn't have to be "Milf_Michelle." I think TER allows a change in username once per year or once every six months. (Anybody have better info on that?)  
.
Do you still have access to the email addresses or other contact info on your former Profile? That could be a way to prove to TER Admin that you (Milf_Michelle) are the same person described in the old Profile. An email to support@ter from the Profile external email would help to connect the dots. I wonder if TER would accept phone or text as proof (or is it too easy to spoof a phone number these days?).  
.
Do you still have access to the email address you used to register the former TER account ("Not_Yet_Milf_Michelle")? That is, some Providers have a more private email address for accounts, memberships, etc. (TER account email = private_michelle@protonmail) but a public email address for "business" listed on their public Profile (Profile and Advertisement email contact = public_michelle@privateoffice).  
.
Do you have any other OLD info that can connect you to that Profile. E.g., did you ever pay for VIP and have a CC number on file? Even if that old CC is expired, it might connect the dots. Who else but the real you would be able to tell TER "I last paid for VIP in May 2016 using CC ending in ####."
.
Sketchier connections might be, "If you check the PMs from that old Profile account owner (me!), you will see:"
"I complained to Admin about a fake review from scam_reviewer. After 2 months and 10+ PMs, you finally removed that review which is why it is no longer there."  
"I sent PMs to mrfisher and impposter thanking them for their helpful advice about topic XYZ."
.
If you can easily connect the current dot (Milf_Michelle) to the former dots (old Profile name, contact info, etc.) with "strong" links, it should be do-able.  
.
Good luck!
