Watermark bug..

The icons look good, fairly easy to use.
But the majority of my icons have a “lordicon” watermark on them.

and the author, the developer doesn’t seem to be eager to fix this.
I’ve emailed him several times, i haven’t gotten a helpful response,

Instead I get spam mail every day from hi@lordicon.

This is frustrating. I need to finish my site, and I’m waiting to no avail.
