STOP DELETERS !! Here's How !! Posted 6-11-2001 05:54

--------------------------------------------------------------------------------
I found this info on stopping deleters as I saw Rocky was having some trouble with them.

DELETERS ERA IS FINISHED! THERE IS A SOLUTION!!!

This works, for those people who upload files...

You upload the files like usual, and you rename it on the server by adding at the end, a space, a dot (.), a (/), a space and a (/)

Example : tarzan.rar will be tarzan.rar ./ /

Only the admin can erase the files.
This solution has been tested with success.

Now you can upload withtout thinking that one of these
ass-hole deleters will ruin it for everyone...

Prikolno, oproboval, poluchilos.

Можно даже без точки: movie.avi / /

Urgent, bez tochki ja proboval, nepomoglo, a s tochkoi polucilos.

Значит, плохо пробовал :
[название_файла][точка][расширение][пробел][форвард][пробел][форвард]
\ - backslash
/ - forward slash
