They got money if we buy Toriprime from them around $10
When you use search button, the data of the post or thread that you want to search will pile up the result with many (or should i say a LOT) of possible result and will appear along with the words that have a similiarity with another words (like if you search word "pass" it will also search something that look similiar like "ass") and this can keep bumping the result like 3x bigger than the normal required results, this will consume the net bandwidth. When the bandwidth has reached the limit, you need a longer bandwidth capability to store it all, and its expensive.
The money from Toriprime are used for this.
This can also occur at forum posts too, that is another reason why spam is prohibited.
At least this what my bro told me, i cant really understand it so i try wrote i can.
