so, sales can only go down after a while, this is normal for everyone.
because your target user already buy premium whehter from yours or others.

@ amartin99
it looks like you are so pround of your spamming.
uploading more content won't necessarily double your sales..
seriously, you have to think from downloaders' perspective, do they really have to buy premium to download your files? how many choices left for them? can they get a uploaded.to links easily? or if they just wait one or 2 hours, can they get other links for the same content that you post?

you can only know the number of clicks of your files, you can't see the actual complete FREE download from netload, people click your links, and they give up easily because of speed is too slow for them. very very few would just buy premium.

i am having something like 1000 unique visitors daily, and i am getting 6 sales daily
i do post to forums, 4 or 5 forums.

but guess what, i used to get 10 sales daily for a whole month, the sales will only decrease, because right target is almost premium already, unless there is new traffic.

and don't think i am spamming, i am uploading less than 30 GB daily.
and i guess you upload to other hosts too.. probably.

the reason why your account is locked might be because you are downloading way too much.
4TB in few days....Jesus..you are trying to kill their bandwidth..and 5 or 6 sales weekly, can't be proundly enough to complain "hey, i am getting them sales..."

actually you're not making them money unless you have rebills, because if you choose Plan 1,and you get 12 dollars for a 1 month premium sale, they are losing money if this user is not going to renew.

of course, netload loves big uploaders who have a site to choose plan 1,and bring them a lot of rebills, they know they lose money in first intial sale,but they want you to keep uploading and posting, so that those users will renew, that's how they earn.

for people who don't have a site, and are only posting to forums to get luck
they probably should choose Plan 1

for people who have a site, they have to switch to rebills plan after some while when they feel sales are decreasing on a daily basis.
