The bad blocks are probably still floating around the network yeah, I don't think anyone is actively trying to mess with it anymore. Just as a test I've resynced v1 a couple of times but I can't get it to crash or anything.
Built the new v1 source successfully. During the new sync, everything goes well for a few minutes then sync stops and memory usage climbs until eventually the app quits. Restarting just repeats the same. Needed a few restarts to get the full sync. I noticed this yesterday (memory usage) when my coinswap was delayed.
Could this be a sign that the attack is ongoing.
