"Everyone wants you to be the person you were [on] the show and that's not always the case," Blake explained.
"I often say you kind of become who you were edited to be. There are a lot of people that want to take advantage of who you are now, and that's hard. You have to keep your old friends close and pick the right new friends."
Blake went on to suggest that no one who goes on Bachelor in Paradise is on the show for the right reasons, genuinely looking for true love.
"I think 100% go on Bachelor in Paradise for followers... It's incredibly easy to meet people in [Bachelor "BN" Nation] once you are in BN. So everyone that touches that beach is there for engagement and followers... And there is nothing wrong with that," Blake explained.
He added, "Imagine if you knew exactly what you had to do in your job to get a promotion... You would 100% do it."
But Blake admitted he's not sure whether he would encourage people to go on The Bachelor or The Bachelorette to begin with.
"I always say it's high risk, high reward," Blake wrote to another person on Thursday.
"You can go have an amazing time and everything that comes with that or you can have a horrible time and be f-cked up for life. At this point it's no secret what this show is capable of. Do your research and know what you are getting into."
Blake finished as the runner-up on Becca's The Bachelorette edition in 2018. The pair's breakup was excruciating to watch considering Blake had said he was madly in love with the show's leading lady at the time.
"I truly thought that if it came down to me proposing, that she wouldn't say no," Blake told Entertainment Tonight in 2018. "I thought what we had was real."
Blake added it was "incredibly hard" to get over his heartbreak at first.
"I still don't regret it, even after everything. But I know a lot of people who do," Blake wrote on his Instagram Story.
However, Blake insisted Bachelor Nation will "always hold a special place" in his heart.
"I'll always be grateful what the show has allowed me to do," Blake told an Instagram user. "But I also don't want to be defined by the show. I hope years from now, people won't say, 'Blake from Bachelorette,' just 'Blake.'"
And finally, Blake assured his fans that his heart is "in a good place these days."
Blake previously detailed why his experience on Bachelor in Paradise was so "toxic" during an interview with Us Weekly.
"[You're forced to] build a relationship with your producer or producers. In that environment, you have nobody else to lean on. [You're experiencing] lack of sleep, you're not eating right, you're drinking. It's very emotional and is easier to get manipulated in that environment, obviously, than in your regular life," Blake explained.
"But at the end of the day, the decisions you make are your own; they can't make you do anything. Now, it is scary in editing when that they can frankenbite and they can take words that you'd say at different times and put that together. That is super scary."
While ABC has yet to officially announce theBachelor in Paradise cast, Reality Steve spoiler blogger Steve Carbone recently reported Becca -- who confirmed she had broken off her engagement to The Bachelorette14 winner Garrett Yrigoyen in September 2020 -- is going to be on Season 7.
