I've noticed over the past few days someone has been entering text like the following into my comment fields :
<a href="http://www.distritofederal.df.gov.br/003/00301009.asp?ttCD_CHAVE=101732&lorcet">lorcet</a>
unendurable imperfections <a href="http://www.distritofederal.df.gov.br/003/00301009.asp?ttCD_CHAVE=101746">phentermine side effects</a>
eolith acidimeter
What is this person trying to achieve, and is there anything I need to do to ensure they don't do anything malicious through my text entry fields?
EDIT
It looks like this site belongs to the Brazilian government. Other sites that have been linked don't even exist. Hence I am a bit skeptical that this is just link spamming..
