what do sync issues have to do with block size?
you obviously have no idea what you are talking about...
and well... its easy to calculate how "much spam attack" we can get with 8mb. just imagine how expansive a 1tb drive is today and how long it takes to get filled... really a big problem

What? Bigger blocks than needed means blockchain open for spam attacks. It's obviously related to sync issues, like we had in early August. You obviously have no idea what we have faced this summer. If your holiday is over, read some Bitcoin news.
