Are you being a troll,
@Wicker? Or is it really a genuine question?
If it is a genuine question, I'm really curious to understand how someone with your length of time on this server, can be so stuck for ideas. I'm not going to accuse you of having a limited imagination, but if you do, that's going to cause you hardship, for sure.
There have been plenty of good ideas already given, so other than support them, I'm not going to repeat them.
I would add that you could also:
- Steal cop cars (not from police-stations though) and drive them away from police just to hamper their ability to keep the Queen's peace. No guns necessary. You can hamstring them for hours and get lots of officers into trouble for not guarding their vehicles better. I can't remember if you can scrap them for cash, but it's worth exploring. Even if you can't you can cause mayhem, and to a rebel, that is meat-and-vegetables.
- Earn money and give it to other civilians. Not violent, but still rebellious. The government doesn't like free-spirits that hand out cash to all and sundry, because it gives them powers and ideas above their stations. Winning hearts and minds is just as 'rebellious' a concept as murdering people.
- Which itself is another option - vigilantism or just extortion, protection-rackets, or plain murderous intent - but of course, you need to do it in RP, usually with lots of reasons and opportunities for the victim to escape with their heart-in-their-mouth and soaking wet pants. Everyone enjoys a good scare; a narrow squeak, if there is plenty of interactivity, banter and scope for different outcomes.
- Stealing from Poseidon - they love a bit of banter and a naughty perp or two on their lands. Just keep it fresh and interesting. Hassle them without using your weapons and you can run them ragged... if you know what you're doing. Of course, the trick is knowing just how far to pump them up, without making them pop yo' ass. Takes skill and imagination.
- Robbery. An old favourite, but hard to do well. Whether it's a fuel station or a greenhorn noob, taking cash without getting caught, and without killing, or even carrying a heavy weapon, is the mark of an expert subterfugist. Can you hack it?
- Meths running - a favourite of mine (allegedly). You can rack up lots of cash doing this, with the right vehicles, skills and deftly-placed housing. Of course, the trick is not to get sussed, which means doing it at night so the fumes can't be seen, banking your chemicals and products in a nearby house (maybe) and only doing the final exchange when the cops are tied up doing something else. You can do this alone or in a small group, with much reward and zero detection, if you're skillful.
- Robbing banks is hard, but not impossible, with merely a rook. If you have a team you can delay the cops and sneak the money out if you are artful. If you are classless, you'll die in a firefight and a torrent of verbal abuse. It's always about finesse, more than firepower.
- As a powerful and influencial rebel, you could even go to the extent of organising 'events' - like races, or fly-bys, or aerobatic displays - and awarding prizes to the winners. Your massive bankroll will pay for the inevitable crashes and hospital bills, plus maybe a few quid to make the cops look the other way one night during a Pygos-Kavala rally which tears up the island at breakneck speed. The community team I am sure would even be prepared to help you organise it, if you'll pay for the prize-money too. Obviously, only a true king-pin of organised crime could pull off such a big PR and recruiting stunt like this, flexing their wealth and their organisational skills to the max in order to impress all the little people on the island. Scrubs probably wouldn't know where to start with such a thing.
- Hell, you could even stand for mayor, and RP with the cops as mayor (if you were good enough to win) and tie them up with all sorts of unnecessary distractions and protection-duties that made life easier for other rebels with their own causes elsewhere, simply by 'thinning out the plod coverage'. It wouldn't last forever, but you could have some fun, demanding escorts, audiences with the senior plod, sending them out to do your shopping, etc, etc.
The point is 'being a rebel' is not necessarily just about 'wearing all the gear and getting into fights'. For the best rebels, it's about hiding in plain sight, making mayhem and destabilising the government or the popo in ways that aren't easily detected, or aren't technically even illegal... or at least are not traceable.
Anything's possible, if you have the imagination.
