I am not sure what you are asking, you can search the site and get feedback on what others say about it.
If you decide you want to attend TPX Top 96, I would suggest that you attend one at a location that has some colleges that you are interested in. Some of the college coaches are listed that will be working the camps:
If you attended a prior showcase, coaches get rosters with contact information.
If a coach has you on their mailing list they may share it with this group to put on the mailing list to send out invitations so players will attend the clinic they are working.
If you had previously signed up to a recruiting service or a on-line baseball recruiting site, possibly they have access to it and put you on their mailing list.
Bottom line, I really don't know what level of play you are and it really does not matter how they got your name and contact information, what matters is if you are interested in what instruction they can give you or what exposure you can get from it, that is why I suggested if you are interested, attend a clinic in the geographic area or one that has the colleges that you may be interested in attending.
