tikShop gives the user tickets to everything on the eShop.
EVERYTHING. Plus, there's the offside chance that Nintendo could start to cross-reference tickets in a future update, which might lead to potential bans.
If you don't want the tickets to be installed on your system, download the content via CIAngel or freeShop.
On the off-chance that you do decide to use tikShop or just want all of those tickets removed, use tikSweep:
