not sure if anyone here is operating a 'url shrinking' service but i thought i would see and give a 'heads up' seeing ive just had 3 sites 'blacklisted / suspended' due to some spammers abusing the service.
i know these type of sites do come at a risk but ive had them running for 2 years without a problem until this week.
if you are running this type of service? try and validate the links against the 'anti-spam' DB before you allow them to become available through on your site(s) as this will save on unwanted emails.
with url shrinking services it basically re-writes the link to something like 'yourdomain.com/fgdtgd' rather then 'spam.com/morespam.html' its good for places like twitter & youtube with t.co / youtu.be.
it opens up the door to be abused which is what happened and had 2 sites 'blacklisted' and there my host closed the accounts given they were on a shared hosting server which affected their i.p address.
miniurl.in / mini-url.in
it was an obvious outcome........maybe a 'heads-uo' for others running such services.
Reaalyy this is some thing new i am coming across.Due to the increase in the use of internet, daily new types of problem are coming.Thanks for sharing the info.We should be aware of this type of facts.
