It so annoying
Explorer During Games
If you mean dailies, then using the opening explorer (as well as books, videos, opening databases, etc) is allowed by the rules and expressly not cheating. What is not allowed is the use of chess engines, tablebases and help from other players.

Explorer and other databases are part of the game--not only allowed but encouraged--in correspondence chess ("Daily"). See http://chessskill.blogspot.com/2011/03/databases-and-their-discontents_28.html where the author notes:
Opposition to Database Use
Many players express the view that use of databases is distinct from putting thought into the game. A chess enthusiast calling herself ChessMom raised this issue stridently on the Red Hot Pawn forums in a thread called "How to learn and not cheat," "you're supposed to play out of your own brain, not somebody else's brain." The thoughtlessness of database use cropped up again in "Nagging Question: Are you for or against the use of Databases, and why?" on Chess.com. Peedee suggested, "[u]sing someone elses [sic] brain for the first 20 moves completely invalidates ANY contest. In fact, getting outside help AT ALL is just nonsense."
Several posters in these threads offer their views that research requires skill.
Every chess player should strive to improve him/herself, and that includes reading and analysing. Correspondence chess gives players a concrete game to study and learn about while playing it. They have the opportunity to play the very best moves they can find by using research techniques.
Fezzik, "Nagging Question"
[I]f things come down to who has the better database OR who is the better researcher, how is this a measure of who is better at playing chess?

I image the cheats are in abundance at your level tacticalprecesion, if the goal of a cheat is to perform well below average, and gloat look at me I suck.
In daily games opening explorer is allowed. However in live chess, opening explorer explicitly isn't allowed. https://support.chess.com/article/317-what-counts-as-cheating-on-chess-com
Why is there an opening explorer during games as it is literally cheating. Any player can go there and see the best moves in an opening they don't know. At least you could hide it from the game and allow you to see it after the game or in casual games. It is so infuriating when an opponent clearly is using it by taking a long time to make a capture. I don't want to be rude to them but they'll just keep doing it. Please do something about it.
