Twitter and other social media platforms have helped make National Signing Day a viral event in recent years, but this year some college football programs have been hit with suspensions on their accounts.

National Signing Day College Football Twitter suspensions

On Tuesday, the Texas Longhorns‘ football Twitter account was briefly suspended. The momentary shutdown shocked many, as Texas’ page was verified and had nearly 190,000 followers.

Then on Wednesday, (National Signing Day) three other universities — Georgia, Missouri and South Florida — also had their Twitter accounts suspended. Those three pages were restored early Wednesday morning.

Add the official @FootballUGA Twitter account to that list. Twitter doesn’t mess around when it comes to copyright. #NSD #Social pic.twitter.com/XsapeQHvRx

Nevertheless, many followers remained perplexed for a brief time.

Very weird. @TexasFootball gets suspended with 189,500 followers and a blue check. Comes back with 12,000 followers and no blue check. And we thought there would be less NSD oddness this year. https://t.co/0QlBPcvBf4 pic.twitter.com/hEYawyFAmq

A person affiliated with Missouri’s football account explained the reason for the suspended pages: copyright violations committed by using songs in promotional videos. The employee also noted that the Tigers have ben using said songs for years but hadn’t been reprimanded for this until now.

Twitter dinged us and probably every other football account for using copyrighted songs. Been using them for years, but they just started making claims in the last week+

There is an act called the Digital Millennium Copyright Act (DMCA) that dictates online accounts are automatically suspended after three violations within a certain period.

Some of Missouri’s and USF’s tweets prompted takedowns as a result of filings by the Recording Industry Association of America (RIAA). Twitter also filed several notices.
