I like to know something about the spam. How do you guys decide that someone is spam?
Attempting to sell something in a support forum. Like renting an apartment in Dubai, for instance. Roku has seen fit to simply move that post of yours to "Off Topic" rather than remove it and remove your account. That's because Roku is nicer than I am.
And the "Off Topic" simply means non-Roku discussion. It doesn't mean sell stuff. On a forum such as this, it's a great place to talk about what's going on with Amazon, Apple, Google, or others that have Roku-like devices. Talking about Doctor Who or the moon landing would be acceptable to most, though, to me, both are not something you'd come to a Roku forum to read.
To your question, any attempt to sell or promote goods and/or services on a Website or forum not for that purpose is spam. But you know that already.
