The Don RX in (Social Media)

[Phobiartz]

I hope that this is the correct place for me to post this? If not, please advice me as to where would be the proper channel to do so. Thank you kindly in advance.

Who is thedonrx?

The issue. 

I have had a follower on one of the social networks I am on. However, I am always following people who have to do with the line of work that I am in. So this fell way out of left field.

Yesterday, I noticed that I am followed by a handle name @thedonrx.

If anyone knows what I am talking about? Please let me know! 

I went to see what it was. It turned out to be a vendor, who
claimed all kinds of medications and anabolics that he has offered, for vending. 

No shame in the name and very bluntly had his website
address on the social network of his home profile page. 

Not an actual web hosting site, it was one of those threads where people list what they got and all that. Basically, what smelled to me like a scam or trap. Now, I could be off.

The list included some of the biggest "red-flagger's" on the market. Like Oxy and Dilaudid. 

Amongst there were others,
like you would normally see in most IOP's. 

What got me alarmed was, how this person found me? I know it could just be a form of trap? Or perhaps something else, like some sort of phishing?
 
Where did this person come from? What can I do to get this person out of my radar? 

I am in the digital domain, however, this was completely different from the types of sites that I visit. I have gotten myself out of most forums that do not pertain to what I am intending to do in my line of work. 

So, this came to me as a surprise.

Thank you for your time! I appreciate any feedback anyone may have.
