Would pointing several domain to a same site hurt SERP?

[llegent]

Hi guys, realizing that some of my domains which are currently parked do received some traffic here and there occasionally, but there seldom incurred any clicks in them and didn't earn me a good income, in fact they were almost zero.

So I am thinking, instead of wasting the potential trafic for these domains, wouldn't it be better if I were to point them to my main site which is developed and ready to received more traffic!

However, I am quite concern as to would doing this could potentially hurt my SERP or not? I have this concern due to such practise might be viewed as "bumping" or "blackhat" trick to the eye of major SE. I have no worries if I only point 2 or 3 domains, but I plan to build up a little bit of my domain portfolio and point them (about 20domains) to the main site, that's why I am little bit concern about this.

Or did I "over" anxious?:p

Should not hurt your serp at all. As long as you do a permanent re-direct the all the pr of those other domains will pass to the domain you are linking to, theortetically.
