Yes, although it is limited in what you can install/do as most shared boxes are. You can also buy a dedicated server from them if you want full control and setup to your own liking.
Links below will give you a better idea about their shared seedboxes.

Not to sound shilly, this is my own personal experience. https://hostingby.design/ - specifically their "app boxes" are great for building buffer. About $11 p/m for 4TB HDD/10TB bandwidth (only upload is counted, download is not).
Never had issues with speed or overcrowding of services. Been with them on and off for 4 years now.
i2p? Really? It's painfully slow for browsing alone.. I can't imagine it's much better when downloading torrents.
People consider IPT hard to maintain ratio? You can literally just save up bonus points and zap HnR's.. It's also super easy to build ratio as they have a good chunk of freeleech everyday. They have one of the easiest to work with IMO.
Buy a cheap seedbox from hostingby.design for $7 per month (all you need is one month). That would give you 3tb of buffer on TL in no time.. You would never have to worry again.
thegeeks.click and bitspyder. Thegeeks is really starting to show it's age though and is becoming quite ancient/lacks good retention and consistent uploading.
I'll be the oddman out and suggest paying the one-time $20 registration fee for iptorrents.com
It's simple,quick and easy. No need to worry about getting invited/waiting for open signups. Their retention and library is huge. Speeds are also wonderful as a lot of people are seeding from seedboxes.. I'm on most cabal/top private trackers and I still use it more than anything. Been using private trackers for 6-7 years now.
It's got everything you would ever need as it's a "general tracker" so they have games,movies,tv,software etc. If you don't want to pay then checkout: https://opentrackers.org/ for trackers that are having public signups.
