Reddit users are prolific and inquisitive, but kind is not a common adjective applied to people on the social networking site where the anonymous comments can often get vicious.

Tommy Castelli expected as much when he posted a simple but desperate query on the Reddit Vancouver board this week: "Looking for Free Food today."

"I am hungry and have no money. I'll save you the sad story, anyone know where i can either get a free bite to eat or food to cook today, I haven't eaten in two days," he posted.

Without knowing that Castelli is a former addict with hepatitis C and liver damage who is battling post-traumatic stress disorder and depression, Reddit users replied with kindness and advice — and then donations.

Redditors messaged Castelli privately and dropped off groceries, fresh bread, and homemade meals as well as warm clothes and some small amounts of cash.

"I was so moved, I kind of expected to get raked over the coals. But as people replied it was clear that folks were being kind," Castelli told The Huffington Post B.C. in an email on Wednesday. "I tried to answer everyone, and well, it turned into so much more."

Castelli also learned about the Sikh religion because some commenters explained how he could go to a Sikh temple for a free meal prepared by volunteers.

The information was especially useful because Castelli tries to avoid the Downtown Eastside, where there are many social services but there is also a lot of drug use.

Castelli says he's been sober for eight months and that "it's been a rough ride." He lives in an SRO (single room occupancy) in downtown Vancouver and relies on a monthly disability payment because health issues currently prevent him from working.

But he does keep busy with a project to get free WiFi for marginalized people living in poverty, starting with his neighbours.

"Not being online in 2014 is like being illiterate for generations past. People living in poverty are already isolated and marginalized," explained Castelli, who completed a college network administration and security program.

"Being online is what fed me. It's how I found a support network to lean on while [in] recovery, it's opened countless doors."

Castelli's experience on Reddit has opened new windows for users there, too.

One Redditor responded to Castelli's update on all the help he had received:
