Oddity with some person sending messages (spammer)

Sometimes I get some spam and when you respond to the person, it immediately types a message (like it is an automative response and not a person). I can type in adadadad for example and it will say “take a look at my profile” and give a link. I say afdasd more and every time, it says one second later “take a look at my profile” and a link. What is this? I won’t click the link but how is that person doing that? Is it a person or just a fake program that can’t read anything I type. I have recievce these before and looked up each profile and most are created on the same date, like they are all intended to be used only one time to prevent a person ignoring them. Here is the example of what was being said. Oh yeah, tehre is hidden text that yo ucan only see when highlighted. The gibberish is the text you can see when it is highlighted. Also, don’t click the links:

rigobertomcintosh17: nasmfHey gary_freespacefanatic, how r u?

This is odd. It can’t be a human. What is this? I was testing it by typing gibberish and it was automatically saying things randomly.
