Facebook tools (msgs) safe levels

Hello ppl! I am a newbe and F****g exited with this tool.
I need help with the following facebook (tools) safe levels:
How many messages is it ok to send pee day to fb pages (and how many to users - does the numbers of msgs include both fb pages and users? ) ?
How many secondary msg (replies) can i send to those who send me messages ?
Offcourse i use spintax but, is it ok to include links?

Couldn’t find anything in the forums.
