I own on Orihuella Costa and love it!
We have never been mugged, driven off the road, or burgled.
It is unfortunate that some people have had bad experiences in OC, but come on, this happens all over Spain AND the UK!
At least in OC we have beautiful beaches, (never seen any faeces personally), and a good infrastucture.
Unlike some urbs where they have all the roads in place, but only a few properties have been built
Some places look like the wild west!
Unfinished urbs are unsightly and there is more risk of being burgled as there are fewer properties/residents to keep an eye on things.
So don't be put off of an area by some geek blogging about it on the web.
Go there, see for yourself and make your own decision.
Stay a while, get the feel of the place, count how many times you are robbed, accosted or burgled.
These things happen to the minority.........
As for the streets full of rubbish.................what a load of rubbish!!
Yes, you get the odd thing put by the bin, they soon get taken away or picked up by the scrap man.
It really isn't THAT bad!!
