Pretty much all 'work from home' schemes are borderline scammy, or badly paid. It's even worse now with the rise of 'disruption' apps and shit like Fivverr or People Per Hour - to be blunt, these sites are a race to the bottom and even if you get work, you are likely to earn about £1 an hour.
Do you have any specific skills, OP? Are you bilingual, can you do bookkeeping or proofreading or transcription? All of those offer some opportunities, but, again, most people who want to hire you will want to pay you as little as possible.
If you can face it, there is phone sex, but it depends on your DC being either good sleepers or out of the house for some of the time (and on you having a certain amount of tolerance for what are mostly extremely boring and repetetive men's sexual fantasies).
There are the sites that offer either money or products for completing surveys but these, again, involve quite a lot of work for not much return (some of the revire-and-keep offers are for things that can be hauled off to Cash Converters afterwards, admittedly.)
I have dabbled in most if not all of these things over the years and what I have found is that sometimes you can make a few quid for a while, and then a million other people discover the same thing, and the money dries up. Some stuff also involves a substantial initial outlay of either cash or time, and making the money back is dependent on luck as much as skill or effort.
