I don't know, last time I did it it worked just fine, perhaps they shouldn't be locked in too small area, like 3x3, but it doesn't have to be that big either for them to flee and take the taming points
if the other ways didn't work then it is better to try than not to try I think
hitting it with 5 characters is also good idea, but it doesn't make the other one bad, because those ideas allow to tame instead of not taming at all
and it's not really inconvenient, opening and closing a gate is just as inconvenient as calling someone else to come instead of doing other tasks - what is the part that makes it more inconvenient? the clicks? well, you also have to press buttons to make openings in order to tame!

I mean, you don't have to open the gate for long enough for them to make a big opening and big damage and heavy wounds, just for the two hits, and then come back and reduce the opening? and just repeat until the end. Is the use of palisade invonvenient because you have to build it? well you do, but it's a trade off that the person can do or not do, it's up to them, and one could use the airlocks that are used for running away from people for that instead of building extra walls, so yeah, if you have airlock gates, you do not have to build anything extra, and if you don't have them then the most of inconvenience is in the palisade building, but it's not the end of the world and still a viable way of taming
everything has it's upsides and downsides
if you want to get more stats for taming, you have to wait, but you can do it without tricks and alone
if you want to call more people, you have to call them to help you, but you don't have wait for stats or use tricks
if you want to use tricks, you have to do the clicking, but you do not have to call the people or wait for raising stats
all of the above ideas work if done properly and it is up to the person to pick the way which suits them best, lolz

he is not "many people", he is himself, perhaps it will work for him?
and the "many people" might have done it in a wrong way!
