Also, this the first "spam" alert I saw. I looked at some meta posts and checked some google results too (for the OP's question) and after a long haul decided to mark it OK (as visualization could be a genuine problem) though I had a hunch I might not pass it and I didn't.
- What exactly is a "spam"? (what is a spam for dummies maybe) Like why/how it happens (intention, goal, procedure, detecting). No site/network is being promoted here via link (may indirectly? or unintentionally? or it is? or is there some other reason?)
- In such reviews will one always fail? So better be skipped if I find okay or otherwise take relevant action?
