I don’t get the feeling these are going to stop anytime soon. Maybe teams will get players to comb through their social media to eras these 5 to 7-year-old or hire people to do it, but I’m sure they’d rather just have their players not have social media, particularly Twitter, but I doubt they’ll be able to make that happen.
And if guys want to complain, “those tweets are old and that’s not who I am anymore,” that’s fine, but take them down.
Think about it like this:
I’m a fan of Player X for years, then he changes teams and joins my favorite team’s rival. OK, so now I don’t like him anymore. So I’m not going to have any Player X paraphernalia anymore. If I don’t get rid of it, people will assume I still like Player X.
I know it’s a childish analogy, but it works the same way with social media. By leaving that stuff up there people will associate those comments with you. If you want people to really think that’s not the human you are today, take the posts down. That way the only person they know is the one you are now.
