I know this is probably the case with every file host, but FS have some pretty dodgy counting stats.
I try to protect my links with .dlc's, so when the .dlc's get downloaded I know pretty much how many people intend to download my files. Even if I be overly pessimistic and say that only 50% of the people who get my dlc's actually download the files, there is still a serious disparity between how many dlc's are downloaded and how many downloads are counted of the actual files.
As an example, I have a dlc that has been download 62 times but the download stats of the files shows between only 3-5~ downloads of each file. This hasn't budged for weeks. Given most of my dlc's have between 50 and 95 links, that is a huge amount of missing downloads.
Some others have many downloads of the dlc's but absolutely zero downloads of the files - and I know for a fact that these files were download by several users as I received confirmation from them.
Other examples of my dlc's abound, but for the sake of brevity I'll move on.
Some might ask why do I think the stats are accurate for the dlc files - well, my answer would be because I don't earn a penny if it is downloaded even a thousand times. They are all smaller than 100KB thus no earnings from them.
On the other hand, I do like FS and it's ability to remote upload from other hosts - namely NL & FSonic. Also, 500GB free storage ain't bad either ;p
Anyway, just my 2c
