When I am downloading a movie/serie, I get across a lot of ACRONYMS that I am not familiar with; TOS is one of them, there are more. If you now the meaning to TOS and any other ACRONYMS and/or abbreviations that are affiliated to downloading movies/series, please let me know. Unfotunately TOS is the only one that I have fresh in my mind. Thanks a lot.
Terms of service ?
It probably means Terms Of Sevice, which means they have rules and they need you to commit to abiding by them.
