That phrase reads like a garbled search query or a sentence written by someone whose English is a little shaky. I think the simplest decoding is: the writer meant something like 'Gwen needs help with Ben on the internet' or 'Gwen needs Ben's help for something online.' Context matters a lot — are we talking about characters from 'Ben 10', a real-life person named Gwen, or a forum thread title? If it's fandom talk, people sometimes shorthand things (no punctuation, no articles), which makes it look weird.
If I had to clean it up for clarity I’d suggest: 'Gwen needs help from Ben with an internet problem' or 'Gwen needs Ben's help for something on the internet.' Those keep the core idea while making the roles clear. In fan contexts you might also see 'Gwen needs help with Ben for internet content' meaning she wants Ben's assistance to make online posts or streams. Personally, I usually try to go with the simplest rephrase that preserves the apparent intent — it saves me from chasing imaginary subplots, and it's more likely to match what the original poster meant.
