How many automated links a month do you build to each web 2.0 property?

Hi Guys

I intend on using some link wheels to link back to my money site, well actually I intend on making them a bit more random and leaving them open so whether you can still call them wheels is another matter, but anyway I was wondering how many links do you build to each individual web 2.0 property each month? I intend on using various methods, i.e. blog commenting, social bookmarks, profile backlinks, ect, to create a more varied profile, but I was wondering what’s the most amount of links using all of these methods combined I should be building to each property/web page a month. I don’t mind pushing the barriers a little bit and been a bit grey/blue hat or whatever it is they call it these days, after all I will be using some automation tools like scrapebox, bookmarking demon, ect, but I am not intending on posting tens of thousands of “nice blog” type comments, they will be relevant and spun, at least above PR 1 or 2, use private proxies, ect, basically all the basic stuff you should do, I have been reading up on how to use these kind of things properly, but I have not found much on roughly how many links you should build to each web 2.0 property, I know I will probably find a whole range of approaches from the ultra cautious to the xrumer ten thousand links to each webpage type approach, but I was wondering what people think is a fairly safe amount, but still takes the risk you need to take to get decent results. So that’s basically it, how many links a month in total do you build to each web 2.0 property? What do you find to be a safe amount?

Many thanks in advance
