Yeah you should have a little more leeway now with the amount of SP you have, but a new user with 15 SP has to treat every comment they make like gold :) The resource credit economy has actually helped a great deal in making spambots less profitable here on Steem, overall levels of robo-auto-spam-posting have decreased greatly. The tradeoff is newer accounts are limited, but I think in general the community at large does a good job of looking out for promising new users and delegating some SP so they can interact. Cheers
