consider that this post is based on anecdotal evidence from a few days back, so it's lagging a little :)
i'm guessing even if you have low sp, if you wait for your mana/rc to charge, you should be ok. new accounts should be ok too as long as they're getting the delegation that'll help them get started.
as far as spam goes, i think the overall activities have simply plummeted for a few days. i'm guessing spammers will be back once things normalize 😆
but as long as it's not too much we should be fine. no platform is free from spammers so..
