A hacking group in the Netherlands promises to publish photos, phone numbers and addresses of LulzSec members in response to similar treatment by LulzSec.
The group TeaMp0ison says in a post that the public exposure of the LulzSec information is imminent.
"Oh and TeaMp0isoN Issue 2 is coming out VERY soon exposing lulzsec members (pictures, addresses, passwords, ips, phone numbers etc)," the group says.

This threat comes apparently from a 17-year-old member of TeaMp0ison who questions LulzSec's technical skills and who was ridiculed by LulzSec.
"[Y]ou posted hashes from public forums and then claimed you doxed us and laughed at the fact that i was 17 years old. [S]top telling yourself that u are hackers," the posting says.
This just a day after LulzSec posted the identities of two of its own members that it claims leaked LulzSec log information. The author of the LulzSec Twitter stream seems to think that law enforcement officials in the U.S. is after at least one of them who goes by the name m_nerva. "Remember this tweet, m_nerva, for I know you'll read it: your cold jail cell will be haunted with our endless laughter," one tweet says.
Meanwhile, LulzSec is keeping up its relentless drumbeat of breaches and takedowns by claiming responsibility for knocking off line two government Web sites in Brazil.
Neither brasil.gov.br nor presidencia.gov.br were accessible as of this afternoon Eastern time, and the main LulzSec Twitter feed issued congratulations to its confederates in that country.
"Our Brazilian unit is making progress. Well done @LulzSecBrazil brothers!" one tweet reads.
In the United Kingdom a 19-year-old man suspected of being a LulzSec member has been charged with being part of the DDoS attack that forced down the Web site of the U.K. Serious Organized Crime Agency.
Meanwhile, LulzSec promises to release by Friday some data it has stolen from sites it has targeted.
