Come on, I think it's a bad idea to post links to a keyboard app that can potentially steal your data! Let people get it from an official source or put a huge disclaimer.
I'm like 99% sure that no one would willing post a link to a file that's bad but if you notice all the access that you allow a swype installation you really have no way of telling what the heck that program can do because it's suppose to have access to all that info anyway! Unless you're a developer and you can rip apart that APK you really have no way of knowing, even a virus scanner might not find this a problem!!
Be wary people! Again, I'm not trying to insult anyone who put a link up or anything like that but you just can never be too careful with personal information. I for one use my phone to check my bank account, login to facebook and to the admin of my work web site. All of which contain sensitive data (to me at least), and all of which pass through the swype keyboard !!
