Both links redirect you to the .mpe1 downloads from Dropbox. Since Dropbox Public folder has no DL count statistic tools, I redirected the Dropbox links over the linkshortener goo.gl, because this site has a count statistic
So don't be afraid, no trojan
Why not just attach the MPE1 file to your first post rather than a link to dropbox? This will also show you how many downloads you're achieving.
Might save you some hassle.
