Cursing and hexing are not part of my usual practice. I think I have only ever tried the "master curse" from Magickal Attack by Gordon Winterfield. And in that case, I don't think it worked despite it supposedly being a heavy duty curse. But it was very instructive to reflect on the instructions given for the sort of emotional energy and intention you needed to feed into the ritual. For 12 days, you had to basically pour in different forms of hatred and anger into the ritual against your intended person. After day 3-4, I realised I simply did not have that level of malice inside of me to sustain it for that long. Additionally, the "Angels of Wrath" book by the same author also talks about using a sense of justice or "balancing the scales" to emotionally power the rituals in those books. This is something I could probably get more onboard with personally.
But regarding cursing / hexing itself, I do not feel like it is an easy form of magick to do. Aside from ethical / moral considerations, my limited experience and reading on the subject tells me you really need to have a large well of the correct emotional intent to really make a curse work properly. For most people, it is more likely that we have the capability for temporary or transient feelings of anger or hatred towards people, but the sort of long lasting bitter emotion that is needed for proper baneful work is not so simple. I wonder if most people have it or not. For me personally, I don't which is why I focus on defensive work or using rituals on astral invisibility to shield myself from possible issues. Cursing, even more than other types of magick, requires especially powerful emotional intent to give it the proper push to work.
Even beyond the emotional core of the curse itself, you also have to deal with the practical aspect of cursing against another person. Magick directed against another person, especially one who is outside of your normal life, can be a tricky thing to get right. In most cases, you would need to find a way to target the curse correctly at the intended person and you would most likely need some element of sympathetic magick to make it happen. In my experience, this ends up being things like finger nails, a picture, a name, or even something directly written by their hand. Some of the stuff like a name or a picture are considered weak links in my eyes and don't work particularly well for targeting a person with magick. The more effective links such as a personal handwritten piece, a strand of hair, or a finger nail are usually quite difficult to obtain from a person, especially one who you are interested in cursing. This by itself adds a lot of complexity to the curse.
Finally, the type of person you are cursing against can add a lot of complexity to the working. Cursing generally tends to fall under the category of malefic or "black magick" for most people. Most major religions have prayers or basic defences against basic curses such as the "evil eye", which especially includes prayers from Catholicism and the duas from Islam. By definition, these are vast religions with a lot of believers, so their faiths already include a basic level of protection inside of them. Against people who do not believe in any form of spirituality, curses could also fizzle out as could other forms of magick aimed against them because their lack of faith can create a shielding of sorts around them. And finally, against other occultists, curses are going to be even tougher to pull off because we have an idea of active spiritual defence, the deeper knowledge to apply them, and the resources to make them work. In all of these cases, especially the occultist, you would need to be persistent and clever in how you design the curses. You would probably need to employ a strategy that involved stripping away magical defences first before actually launching a well designed curse. Then you would need to keep up the heat in some cases in order to overcome defences that might attempt to re-establish themselves. Something like this falls more into the category of hard highly skilled work than something "easy".
I don't think cursing is an easy form of magick. Most forms of baneful magick could be quite difficult to pull off for reasons that I have listed above. You would also have to deal with blowback from curse work as well. In my case, I did not do curse work that gave me blowback, but love magick. However, that type of love magick involved a more targeted element to it, which gave me a large backlash in the form of a lesson that I took to heart later. You will find with such blunt forms of magick that this can be more common than you expect and it is something that adds yet another layer of problems to performing that type of magick. In general, magick that is used to attract things to you in a general sense (e.g. dates, money, good luck, propserity) is far easier to make successful than magick that bluntly targets a specific person and this type of magick tends to leave less blow back. To manage that backlash, you would need to consider invoking your own protection properly before actually unleashing the curse itself. So to me, curse work is actual quite difficult for all these reasons.
Of course, your mileage may vary, but this is my analysis on it.
