That is what I would be doing! Creating people many free google accounts and then using 7 zip to split the large files into 14GB files. Then uploading thm.
I know there may be services like this but they don't offer 1tb of storage (I could always go up to 3tb)!
I also know that if you want free unlimited storage then you could use UTorrent. But I think my idea is better.
If you want a terabyte of raw storage go to weiyun.com/disk/index-en.html (WARNING! IT IS NOT IN ENGLISH). You can only upload a gigabyte of storage per session that you are using it so it isn't very good!
