There is no control, no policing, no punishment (at least to my knowledge). And as noted on the NCAA website, a "booster" is not what you or I may think of as a booster. One of the definitions used for a booster is "Been involved otherwise in promoting university athletics" which I understand as being everyone here and on Twitter.
Again I don't believe there are repercussions for it but IMO it's a bad look. That's just my opinion and I also wouldn't want to jeopardize the program in any way, shape, form and while unlikely here why invite the opportunity.
