Well, honestly, I think the kid likes the attention. I have a hard time believing that he doesn't want all of these responses and all of this attention that he is getting from this crap.
If you don't want random people to say stuff to you on FB, you can change your settings so that they can't.
Twitter also has options to make your tweets private and protected. I think people might still be able to mention/tag you though. I'm not 100% sure, but I do know that FB has plenty of options and settings that you can make sure all of these random fans that "are a bit too much" aren't able to comment/message/talk to you.
I don't know if he was messing around and thought it was funny, but I'm not really sure what he thought was going to happen. Hopefully he understands that there are idiots in every fanbase and I'd like to believe they account for the minority in the Iowa fanbase.
The kid should do what he wants and maybe think about keeping this a more personal thing, rather than ask everyone in the world who happens to look at his FB page or twitter for insight on which college he should attend.
Iowa fans will say Iowa.
MSU fans will say MSU.
Alabama fans will say Alabama.
And so on and so forth.
...While typing this I took a break to read some of the tweets people were sending him... Wow.... Just...Wow.
It just seems like a whole lot of immaturity at it's finest... and I'm not talking specifically about Jaleel either...
Edit: You can block people on Twitter, but maybe he isn't aware of that option, because he just seems to fire back to anyone who gives him a reason. He responded to 1 guy's tweet with 3 separate tweets, because he didn't respond.
The guy said:
"I hate the hawkeyes but quit being a damn ***** and drama queen. Players like you is what's wrong with college football"
Then Jaleel responded (in chronological order):
"hahahaha"
(No response)
"thank you...don't stop your hating. Keep it coming I love it!!"
(No response)
"players like me? Explain yourself"
It almost seems to me like he is just bored out of his mind or something.
I don't know Jaleel and what I think could be way off base from what he is really thinking/trying to do. It just seems weird. Hopefully people will stop messaging him and just let him figure everything out for himself or with the help of close family or friends if he really is confused.
