Downloading ModTools 1.5 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Tim Parnell. We recommend checking the downloaded files with any free antivirus. The software lies within Internet & Network Tools, more precisely Browser extensions.
From the developer:
ModTools makes it quick and easy to check StopForumSpam for spam accounts, and bdea.cc for disposable email addresses. The idea is to make the life of a forum moderator just slightly easier. This allows you to quickly and easily verify fake accounts prior to banning them.
You may want to check out more software for Mac, such as WiPhA Installer, ImageGREP or VisComPic, which might be similar to ModTools.
