It does matter. It's the only reason why when you use a certain script you get banned in a few hours, Jagex compare your movements to other people's movements therefore if you bot a shit ton and play stupid hours they are more likely to receive this information quicker than if you bot say 6 hours per day. If Jagex didn't care then we wouldn't have to constantly create new bots to succeed the older bots.
I don't get why you guys are trying to test this bot's detectability so hard. Okay so Jagex doesn't know what client you're using but then a bunch of people start playing 24/7 doing the same thing over and over and you think they won't start to work harder to detect this? Why not bot normally to try and prolong this bot's success rather than going crazy with it before it's even started.
The only thing I don't like is when you click new content and all you see is gold trading threads. Quite annoying that they can bump them so regularly.
I'd change the RAM to just 8GB, the PSU is also on the small side. If you want to upgrade any parts in the future such as the GPU to a 760/770 series then you'll need to upgrade the PSU. Personally I always buy a 600W PSU as you can't go wrong with it. Check out the OCZ ModXStream pro, i've had mine for years and have had no hiccups!
Slayer and cannon would be better xp but would also cost a lot too so it's up to you. I'd go with using the cannon on shit tasks to get them out the way.
Maybe a bit too much going there's no clear focal point it's kind of a...well mess really! I'd call it an organised mess though because it is still a good tag I can see the effort you've put in just too messy for me.
The spaceship one is definitely the best, the colours, depth and creativity is all there! The Harry Potter one (to me) looks like a render on a stock nothing really special in my eyes.
One day I will enter this competition, shame I really love doing Movie tags!
