How do i protect myself from gold diggers (serious)

Hey guys, so recently a girl has messaged me on Instagram, using WSO as an icebreaker (basically she identified me from several posts I made here), and was basically all flirty. Anyways, since no sane girl would stalk a guy (much less from WSO to Instagram) and then cold message him (a non-target move), she must be a gold digger. 
 

She was really knowledgeable about the industry, as she asked if I worked in my bank's top group that's not as well known as GS TMT for example (for example, if I worked at PJT, she asked if I was in restructuring or M&A). In addition, she mentioned stuff about my alma mater (like investment clubs, IB workshops, etc), even though she didn't go there. She also subtly brought up the topic of comp as she said something like "ahaha I bet your bonuses for 2021 are going to be amazing because of increased capital markets activity and dry powder" (not paraphrasing, the actual message was less technical).

This got me thinking, since I'm an attractive Oxbridge and HSW alumni who works at a top PE MF, how do I adequately ensure gold diggers don't target me? I know some of them are dangerously smart, even offering to pay on the first few dates or bringing up her "rich dad" so people don't think she's poor and trying to find a sugar daddy. 
 

Some solutions I've brainstormed:

- Delete LinkedIn so people can't find out my job just by knowing my name (I don't need to recruit for anything anyways, I've already exit opp'ed)

- Dress more poorly (maybe time to ditch the Lobbs cap toes)

- Move out of Murray Hill/SoHo and go to a poorer/less materialistic neighbourhood

- Sell my car and drive an absolute trainwreck

- Show subtle signs of poverty, such as yellowed teeth, forcing a Southern/country accent, etc 

- Mention to girls that I would love to work in finance/big law/MBB/medicine because it's so lucrative (so subtly saying I don't work in a well paying profession)
