My question is if someone can ask to many questions on this site or are they allowed to ask as many questions as they want?
A user may ask only...
- 50 questions over any 30-day period
- six questions over any 24-hour period
- one question over any 30-second period
- users with less than 125 reputation can only post questions every 20 minutes
The 30-day limit was introduced on 29 April 2011, and at the moment of writing it only applies to Stack Overflow, Server Fault and Super User. Beware that deleting existing questions will probably not circumvent this limit, and may actually make things worse.
The 30-second and "only post questions every 20 minutes" limits are anti-spam/bot measures.
So in accordance with this, you can ask as many questions as you want, as long as they are all about blender and not off-topic. It's better to have several unique questions as opposed to a single post containing many. The idea is to keep it simple and organized so others can easily find information down the line.
