So it was sorta like trial thing or "demo" if you wanna call it. I wasn't paying much attention while downloading "all the magazines
for free 
"
I got the idea when i got the pirated copy of ___ magazine from pirate site which had calibre written on it so i thought maybe the dude who uploaded got directly from calibre in simply fetch news way BUT he must have been a paid subscriber.
I have downloaded alot of magazines in past few days and only one was completely downloaded
from a to z although all of them have downloaded with just the current week's cover and 2/3 pages more with hotlinks.
